现在的每一行的列都已经有了 `div` 元素。 这已经足够了， 现在让我们添加 `button` 元素吧。
|
||||
|
||||
每一个 class 属性为 `well` 的 `div` 元素内都应该放三个 `button` 元素。
|
||||
|
||||
# --hints--
|
||||
|
||||
每一个 class 属性为 `well` 的 `div` 元素内都应该放三个 `button` 元素。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div.well:eq(0)').children('button').length === 3 &&
|
||||
$('div.well:eq(1)').children('button').length === 3
|
||||
);
|
||||
```
|
||||
|
||||
总共有 6 个 `button` 元素。
|
||||
|
||||
```js
|
||||
assert($('button') && $('button').length > 5);
|
||||
```
|
||||
|
||||
确保所有 `button` 元素都有闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|

);

Font Awesome 是一个非常便利的图标库。 这些图标可以是网络字体，也可以是一张矢量图。 这些图标就和字体一样， 不仅能通过像素单位指定它们的大小，它们也同样会继承父级 HTML 元素的字号。
|
||||
|
||||
# --instructions--
|
||||
|
||||
为 info 按钮添加 Font Awesome `info-circle` 图标，delete 按钮添加 `trash` 图标。
|
||||
|
||||
**注意：** 下述要求中的 `i` 元素也可以用 `span` 元素代替。
|
||||
|
||||
# --hints--
|
||||
|
||||
应在 `info` 按钮元素中添加一个 `<i class="fas fa-info-circle"></i>`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('.btn-info > i').is('.fas.fa-info-circle') ||
|
||||
$('.btn-info > span').is('.fas.fa-info-circle')
|
||||
);
|
||||
```
|
||||
|
||||
应在 `delete` 按钮元素中添加一个 `<i class="fas fa-trash"></i>`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('.btn-danger > i').is('.fas.fa-trash') ||
|
||||
$('.btn-danger > span').is('.fas.fa-trash')
|
||||
);
|
||||
```
|
||||
|
||||
每个 `i` 元素都应有一个闭合标签，`<i class="fas fa-thumbs-up"></i>` 在 `like` 标签元素中。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/i>|<\/span/g) &&
|
||||
code.match(/<\/i|<\/span>/g).length > 2 &&
|
||||
($('.btn-primary > i').is('.fas.fa-thumbs-up') ||
|
||||
$('.btn-primary > span').is('.fas.fa-thumbs-up'))
|
||||
);
|

# --description--
|
||||
|
||||
Font Awesome 是一个非常便利的图标库。 我们可以通过 webfont 或矢量图的方式来使用这些图标。 这些图标就和字体一样， 不仅能通过像素单位指定它们的大小，它们也同样会继承父级 HTML 元素的字体大小。
|
||||
|
||||
可以将 Font Awesome 图标库添加至任何一个 web app 中，方法很简单，只需要在 HTML head 标签中添加以下代码即可：
|
||||
|
||||
```html
|
||||
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css" integrity="sha384-50oBUHEmvpQ+1lW4y57PTFmhCaXp0ML5d60M1M7uH2+nqUivzIebhndOJK28anvf" crossorigin="anonymous">
|
||||
```
|
||||
|
||||
在这个挑战中，我们已经为你在页面上添加好了 Font Awesome 图标库。
|
||||
|
||||
`i` 元素原本是用来表示斜体文字内容的；不过现在，用它来表示图标也很常见。 只需要为 `i` 元素添加相应的 class 就可以让它展示图标，比如：
|
||||
|
||||
```html
|
||||
<i class="fas fa-info-circle"></i>
|
||||
```
|
||||
|
||||
同时，我们也可以使用 `span` 元素来展示图标。
|
||||
|
||||
# --instructions--
|
||||
|
||||
请使用 Font Awesome 来为我们的点赞按钮添加一个 `thumbs-up` 图标，只需添加一个 class 包含 `fas` 和 `fa-thumbs-up` 的 `i` 元素即可。 同时，请记得保留图标之后的文字内容 `Like`。
|
||||
|
||||
# --hints--
|
||||
|
||||
应添加一个 class 包含 `fas` 和 `fa-thumbs-up` 的 `i` 元素。
|
||||
|
||||
```js
|
||||
assert($('i').is('.fas.fa-thumbs-up') || $('span').is('.fas.fa-thumbs-up'));
|
||||
```
|
||||
|
||||
Like 按钮中应包含 `fa-thumbs-up` 图标。
|
||||
|
||||
```js
|
||||
assert(
|
||||
($('i.fa-thumbs-up').parent().text().match(/Like/gi) &&
|
||||
$('.btn-primary > i').is('.fas.fa-thumbs-up')) ||
|
||||
($('span.fa-thumbs-up').parent().text().match(/Like/gi) &&
|
||||
$('.btn-primary > span').is('.fas.fa-thumbs-up'))
|
||||
);
|
||||
```
|
||||
|
||||
`i` 元素应出现在 `button` 元素内。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('button').children('i').length > 0 ||
|
||||
$('button').children('span').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
表示图标的元素应有闭合标签。
|
||||
|
||||
```js
|
||||
assert(code.match(/<\/i>|<\/span>/g));
|
||||
```

# --description--
|
||||
|
||||
回忆一下，除了可以给元素添加 class 属性，我们还可以给元素设置 `id` 属性。
|
||||
|
||||
每个元素的 id 都必须是唯一的，并且在一个页面中只能使用一次。
|
||||
|
||||
让我们为每个 class 为 `well` 的 `div` 元素添加一个唯一的 id。
|
||||
|
||||
记住，可以这样给一个元素设置 id：
|
||||
|
||||
```html
|
||||
<div class="well" id="center-well">
|
||||
```
|
||||
|
||||
给左边的块设置 id 为 `left-well`。 给右边的块设置 id 为 `right-well`。
|
||||
|
||||
# --hints--
|
||||
|
||||
左边的 `well` 的 id 应为 `left-well`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('.col-xs-6').children('#left-well') &&
|
||||
$('.col-xs-6').children('#left-well').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
右边的 `well` 的 id 应为 `right-well`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('.col-xs-6').children('#right-well') &&
|
||||
$('.col-xs-6').children('#right-well').length > 0
|
||||
);
|
||||
```

Bootstrap 还有另外一种按钮 class 属性叫做 `btn-default`。
|
||||
|
||||
为所有的 `button` 元素增加两个 class： `btn` 和 `btn-default`。
|
||||
|
||||
# --hints--
|
||||
|
||||
应该将 `btn` class 添加到所有的 `button` 元素中。
|
||||
|
||||
```js
|
||||
assert($('.btn').length > 5);
|
||||
```
|
||||
|
||||
应该将 `btn-default` class 添加到每一个 `button` 元素中。
|
||||
|
||||
```js
|
||||
assert($('.btn-default').length > 5);
|
||||
```

Bootstrap 有着丰富的预定义按钮颜色。 浅蓝色的 `btn-info` class 通常用在备选操作上。
|
||||
|
||||
在 `Like` 按钮下方创建包含文本 `Info` 的块级 Bootstrap 按钮，然后为该按钮添加 Bootstrap 的 `btn-info` 和 `btn-block` classes。
|
||||
|
||||
注意：这些按钮仍然需要 `btn` 和 `btn-block` classes。
|
||||
|
||||
# --hints--
|
||||
|
||||
应创建一个新的包含 `Info` 文本的 `button` 元素。
|
||||
|
||||
```js
|
||||
assert(new RegExp('info', 'gi').test($('button').text()));
|
||||
```
|
||||
|
||||
两个按钮的 class 属性应该包含 `btn` 和 `btn-block`。
|
||||
|
||||
```js
|
||||
assert($('button.btn-block.btn').length > 1);
|
||||
```
|
||||
|
||||
新按钮的 class 属性应该含有 `btn-info`。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn-info'));
|
||||
```
|
||||
|
||||
确保所有的 `button` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|

);

可以使用 Bootstrap 将顶部的元素居中来美化页面。 只需要将 `h2` 元素的 class 属性设置为 `text-center` 就可以实现。
|
||||
|
||||
记住：可以为一个元素添加多个 classes ，class 间通过空格分隔，就像这样：
|
||||
|
||||
```html
|
||||
<h2 class="red-text text-center">your text</h2>
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
应使用 `text-center` class 将 `h2` 元素居中。
|
||||
|
||||
```js
|
||||
assert($('h2').hasClass('text-center'));
|
||||
```
|
||||
|
||||
`h2` 元素应具有 `red-text` class。
|
||||
|
||||
```js
|
||||
assert($('h2').hasClass('red-text'));
|
||||
```

title: 创建一个 Bootstrap 块级元素按钮

# --description--
|
||||
|
||||
一般情况下，`btn` 和 `btn-default` 两个 classes 修饰的 `button` 元素宽度与它包含的文本相同， 举个例子：
|
||||
|
||||
```html
|
||||
<button class="btn btn-default">Submit</button>
|
||||
```
|
||||
|
||||
这个按钮的宽度应该和文本 `Submit` 的宽度相同。
|
||||
|
||||
<button class='btn btn-default'>提交</button>
|
||||
|
||||
通过为按钮添加 class 属性 `btn-block` 使其成为块级元素，按钮会伸展并填满页面的整个水平空间，后续的元素会流到这个块级元素的下方，即 "另起一行"。
|
||||
|
||||
```html
|
||||
<button class="btn btn-default btn-block">Submit</button>
|
||||
```
|
||||
|
||||
这个按钮会 100% 占满所有的可用宽度。
|
||||
|
||||
<button class='btn btn-default btn-block'>提交</button>
|
||||
|
||||
注意，这些按钮仍然需要 `btn` 这个 class。
|
||||
|
||||
给刚创建的 Bootstrap 按钮添加 Bootstrap 的 `btn-block` class。
|
||||
|
||||
# --hints--
|
||||
|
||||
按钮仍然应该有 `btn` 和 `btn-default` class。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
|
||||
```
|
||||
|
||||
按钮应该有 `btn-block` class。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn-block'));
|
||||
```
|
||||
|
||||
所有 `button` 元素都应该有闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||||
);
|

Bootstrap 的 `button` 元素有着独有的、比默认 HTML 按钮更好的样式风格。
|
||||
|
||||
在较大的小猫图片下方创建新的 `button` 元素。 为它添加 `btn` 与 `btn-default` 两个 classes 和 `Like` 文本。
|
||||
|
||||
# --hints--
|
||||
|
||||
应创建一个新的包含 `Like` 文本的 `button` 元素。
|
||||
|
||||
```js
|
||||
assert(
|
||||
new RegExp('like', 'gi').test($('button').text()) &&
|
||||
$('img.img-responsive + button.btn').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
新的按钮元素应该有两个 classes: `btn` 和 `btn-default`。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
|
||||
```
|
||||
|
||||
保证所有 `button` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||||
);
|

现在，来运用 HTML、CSS 和 Bootstrap 从头开始做点东西。
|
||||
|
||||
接下来将会搭建一个 jQuery playground，以便在后续的 jQuery 课程中使用它。
|
||||
|
||||
首先，创建一个包含 `jQuery Playground` 文本内容的 `h3` 元素。
|
||||
|
||||
通过给 `h3` 元素设置 Bootstrap 的 `text-primary` class 属性来为其上色，然后添加 Bootstrap 的 `text-center` class 属性使其文本居中显示。
|
||||
|
||||
# --hints--
|
||||
|
||||
为页面添加一个 `h3` 元素。
|
||||
|
||||
```js
|
||||
assert($('h3') && $('h3').length > 0);
|
||||
```
|
||||
|
||||
确保 `h3` 元素有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/h3>/g) &&
|
||||
code.match(/<h3/g) &&
|
||||
code.match(/<\/h3>/g).length === code.match(/<h3/g).length
|
||||
);
|
||||
```
|
||||
|
||||
为了确保成功上色，`h3` 元素应该具有 `text-primary` class。
|
||||
|
||||
```js
|
||||
assert($('h3').hasClass('text-primary'));
|
||||
```
|
||||
|
||||
为了确保文本居中显示，`h3` 元素应该具有 `text-center` class。
|
||||
|
||||
```js
|
||||
assert($('h3').hasClass('text-center'));
|
||||
```
|
||||
|
||||
`h3` 元素文本内容为 `jQuery Playground`。
|
||||
|
||||
```js
|
||||
assert.isTrue(/jquery(\s)+playground/gi.test($('h3').text()));
|
||||
```

|

这次为内联元素创建一个 Bootstrap 栅格系统的 Row（行）。
|
||||
|
||||
在 `h3` 标签下方创建一个 class 属性为 `row` 的 `div` 元素。
|
||||
|
||||
# --hints--
|
||||
|
||||
`h3` 元素下应该增加一个 `div` 元素。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div').length > 1 &&
|
||||
$('div.row h3.text-primary').length == 0 &&
|
||||
$('div.row + h3.text-primary').length == 0 &&
|
||||
$('h3.text-primary + div.row').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
`div` 元素的 class 属性应为 `row`。
|
||||
|
||||
```js
|
||||
assert($('div').hasClass('row'));
|
||||
```
|
||||
|
||||
`row div` 应该内嵌于 `container-fluid div`。
|
||||
|
||||
```js
|
||||
assert($('div.container-fluid div.row').length > 0);
|
||||
```
|
||||
|
||||
确保所有 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length

并不是所有 class 属性都需要有对应的 CSS 样式。 有时候我们设置 class 只是为了更方便地在 jQuery 中选中这些元素。
|
||||
|
||||
为每一个 `button` 元素添加 `target` class。

为 Cat Photo App 做一个导航，把标题和惬意的猫咪图片放在同一行。
|
||||
|
||||
记住，由于 Bootstrap 使用了响应式栅格系统，可以很方便的把元素放到一行以及指定元素的相对宽度。 大部分的 Bootstrap 的 class 都能用在 `div` 元素上。
|
||||
|
||||
把第一张图片和 `h2` 元素用一个简单的 `<div class="row">` 元素包裹起来。 再用 `<div class="col-xs-8">` 包裹 `h2` 元素，用 `<div class="col-xs-4">` 包裹我们的图片，这样它们就能位于同一行了。
|
||||
|
||||
注意现在图片是否与文字大小一致呢？
|
||||
|
||||
# --hints--
|
||||
|
||||
`h2` 元素和最上方的 `img` 元素应该一起内嵌于具有 `row` class 的 `div` 元素内。
|
||||
|
||||
```js
|
||||
assert($('div.row:has(h2)').length > 0 && $('div.row:has(img)').length > 0);
|
||||
```
|
||||
|
||||
最上方的 `img` 元素应该内嵌于含有 `col-xs-4` class 的 `div` 元素中。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div.col-xs-4:has(img)').length > 0 &&
|
||||
$('div.col-xs-4:has(div)').length === 0
|
||||
);
|
||||
```
|
||||
|
||||
`h2` 元素应该内嵌于含有 `col-xs-8` class 的 `div` 元素中。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div.col-xs-8:has(h2)').length > 0 &&
|
||||
$('div.col-xs-8:has(div)').length === 0
|
||||
);
|
||||
```
|
||||
|
||||
确保每一个 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length
|

);

Bootstrap 有一个叫作 `well` 的 class，作用是使界面更具层次感。
|
||||
|
||||
在每一个 class 属性为 `col-xs-6` 的 `div` 元素中都嵌入一个带有 `well` class 的 `div` 元素。
|
||||
|
||||
# --hints--
|
||||
|
||||
应在每一个 class 属性为 `col-xs-6` 的 `div` 元素中添加一个带有 `well` class 的 `div` 元素。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-6').not(':has(>div.well)').length < 1);
|
||||
```
|
||||
|
||||
两个 class 为 `col-xs-6` 的 `div` 元素都应该嵌入一个 class 为 `row` 的 `div` 元素。
|
||||
|
||||
```js
|
||||
assert($('div.row > div.col-xs-6').length > 1);
|
||||
```
|
||||
|
||||
确保所有的 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length

);

title: 用 Bootstrap 来取代我们之前的自定义样式

|

现在可以清理一下之前代码，用 Bootstrap 的内置样式来替换之前定义的样式，这样 Cat Photo App 看起来更简洁些。
|
||||
|
||||
别担心——以后会有大把时间来自定义 CSS 样式的。
|
||||
|
||||
删除 `style` 元素里的 `.red-text`，`p`，和 `.smaller-image` CSS 定义，使 `style` 元素只留下 `h2` 和 `thick-green-border`。
|
||||
|
||||
删除包含死链接的 `p` 元素。 然后将 `h2` 的 `red-text` class 替换为 Bootstrap 的 `text-primary` class。
|
||||
|
||||
最后，从第一个 `img` 元素中删除 `smaller-image` class，并将其替换为 `img-responsive` class。
|
||||
|
||||
# --hints--
|
||||
|
||||
`h2` 元素不应该有 `red-text` class。
|
||||
|
||||
```js
|
||||
assert(!$('h2').hasClass('red-text'));
|
||||
```
|
||||
|
||||
`h2` 元素应有 `text-primary` class。
|
||||
|
||||
```js
|
||||
assert($('h2').hasClass('text-primary'));
|
||||
```
|
||||
|
||||
段落元素（p）不应该再使用 `Monospace` 字体。
|
||||
|
||||
```js
|
||||
assert(
|
||||
!$('p')
|
||||
.css('font-family')
|
||||
.match(/monospace/i)
|
||||
);
|
||||
```
|
||||
|
||||
移除第一张图片的 `smaller-image` class 属性。
|
||||
|
||||
```js
|
||||
assert(!$('img').hasClass('smaller-image'));
|
||||
```
|
||||
|
||||
给第一张图片添加 `img-responsive` class 属性。
|
||||
|
||||
```js
|
||||
assert($('.img-responsive').length > 1);
|
||||
```

也可以通过 jQuery 根据每个按钮唯一的 id 来定位出它们。
|
||||
|
||||
给每一个按钮设置唯一的 id，以 `target1` 开始，`target6` 结束。
|
||||
|
||||
确保 `target1` 到 `target3` 在 `#left-well` 之中，`target4` 到 `target6` 在 `#right-well` 之中。
|
||||
|
||||
# --hints--
|
||||
|

其中一个 `button` 元素应该有 id `target1`。
|
||||
|
||||
```js
|

assert(
|
||||
$('#left-well').children('#target1') &&
|
||||
$('#left-well').children('#target1').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
其中一个 `button` 元素应该有 id `target2`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('#left-well').children('#target2') &&
|
||||
$('#left-well').children('#target2').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
其中一个 `button` 元素应该有 id `target3`。
|
||||
|
||||
```js
|

assert(
|
||||
$('#left-well').children('#target3') &&
|
||||
$('#left-well').children('#target3').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
其中一个 `button` 元素应该有 id `target4`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('#right-well').children('#target4') &&
|
||||
$('#right-well').children('#target4').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
其中一个 `button` 元素应该有 id `target5`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('#right-well').children('#target5') &&
|
||||
$('#right-well').children('#target5').length > 0
|
||||
);
|

```
|
||||
|

其中一个 `button` 元素应有 id `target6`。
|

```js
|

assert(
|

现在确保页面所有内容都可以响应移动端。

为了让页面逻辑更清晰，每个 wells 都标上它们的 id 吧。
|
||||
|
||||
在 left-well 的上一层，class 属性为 `col-xs-6` 的 `div` 元素里面，增加一个文本为 `#left-well` 的 `h4` 元素。
|
||||
|

在 right-well 的上一层，class 属性为 `col-xs-6` 的 `div` 元素里面，增加一个文本为 `#right-well` 的 `h4` 元素。
|

# --hints--
|

现在把表单里的 `input` 元素和 submit `button` （提交按钮）放在同一行。 跟着之前的做法来就行：准备好一个具有 `row` class 的 `div` 元素还有几个具有 `col-xs-*` class 的 `div` 元素。
|
||||
|
||||
先把表单的 text `input` （文本输入框）和 submit `button` （提交按钮）放进具有 `row` class 的 `div` 中。 再用 `col-xs-7` class 的 div 包裹表单的 text `input` （文本输入框）， `col-xs-5` class 的 `div` 包裹表单的 submit `button` （提交按钮）。
|
||||
|
||||
这是我们到目前为止 Cat Photo App 的最后一个挑战了。 祝你编码愉快。
|
||||
|
||||
# --hints--
|
||||
|
||||
确保提交按钮和文本输入框都在同一个具有 class 属性 `row` 的 div 元素中。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div.row:has(input[type="text"])').length > 0 &&
|
||||
$('div.row:has(button[type="submit"])').length > 0
|
||||
);
|
||||
```
|
||||
|
||||
表单的文本输入框应该嵌入到 `col-xs-7` class 属性的 div 内。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-7:has(input[type="text"])').length > 0);
|
||||
```
|
||||
|
||||
表单的提交按钮应该嵌入到 `col-xs-5` class 属性的 div 内。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-5:has(button[type="submit"])').length > 0);
|
||||
```
|
||||
|
||||
确保每一个 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|

code.match(/<\/div>/g).length === code.match(/<div/g).length

首先，在已有的图片下面添加一张新的图片。 设置其 `src` 属性为 `https://bit.ly/fcc-running-cats`。
|
||||
|
||||
如果图片的大小恰恰和我们手机屏幕尺寸大小一样自然是最好的。
|
||||
|
||||
幸运的是，现在通过 Bootstrap，我们仅仅只需要为 image 标签上设置 class 属性为 `img-responsive` ， 就可以让它完美地适应你的页面的宽度了。
|
||||
|
||||
# --hints--
|
||||
|
||||
该页面共有两张图片。
|
||||
|
||||
```js
|
||||
assert($('img').length === 2);
|
||||
```
|
||||
|
||||
新的图片应该在旧的图片下面并且有值包含 `img-responsive` 的 class 属性。
|
||||
|
||||
```js
|
||||
assert($('img:eq(1)').hasClass('img-responsive'));
|
||||
```
|
||||
|
||||
新图片的 class 不应该包含 `smaller-image`。
|
||||
|
||||
```js
|
||||
assert(!$('img:eq(1)').hasClass('smaller-image'));
|
||||
```
|
||||
|
||||
新图片的 `src` 属性值应该为 `https://bit.ly/fcc-running-cats`。
|
||||
|
||||
```js
|
||||
assert($('img:eq(1)').attr('src') === 'https://bit.ly/fcc-running-cats');
|
||||
```
|
||||
|
||||
确保新的 `img` 元素有一个闭合的尖括号。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<img/g) &&
|
||||
code.match(/<img[^<]*>/g).length === 2 &&
|
||||
code.match(/<img/g).length === 2
|
||||
);
|
||||
```

Bootstrap 的 `col-xs-*` 可应用于所有的 `form` 元素上，包括复选框！ 这样就可以不必关注屏幕大小，均匀地把复选框放在页面上了。
|
||||
|
||||
# --instructions--
|
||||
|
||||
将所有三个复选框都放置于一个 `<div class="row">` 元素中。 然后分别把每个复选框都放置于一个 `<div class="col-xs-4">` 元素中。
|
||||
|
||||
# --hints--
|
||||
|
||||
将所有的复选框嵌入一个含有 `row` class 的 `div` 元素中。
|
||||
|
||||
```js
|
||||
assert($('div.row:has(input[type="checkbox"])').length > 0);
|
||||
```
|
||||
|
||||
每一个复选框应该嵌套于单独的具有 `col-xs-4` class 的 `div` 元素中。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-4:has(input[type="checkbox"])').length > 2);
|
||||
```
|
||||
|
||||
确保所有 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length

Bootstrap 的 `col-xs-*` class 也可以用在 `form` 元素上！ 这样就可以在不关心屏幕大小的情况下，将的单选按钮均匀的平铺在页面上。
|
||||
|
||||
将所有单选按钮放入 `<div class="row">` 元素中。 再用 `<div class="col-xs-6">` 元素包裹每一个单选按钮。
|
||||
|
||||
**注意：** 提醒一句，单选按钮是 type 为 `radio` 的 `input` 元素。
|
||||
|
||||
# --hints--
|
||||
|
||||
所有的单选按钮应该放置于具有 `row` class 的 `div` 元素中。

||||
|
||||
```js
|
||||
assert($('div.row:has(input[type="radio"])').length > 0);
|
||||
```
|
||||
|
||||
每一个单选按钮应该嵌套于具有 class 属性为 `col-xs-6` 的 `div` 元素之中。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-6:has(input[type="radio"])').length > 1);
|
||||
```
|
||||
|
||||
确保所有 `div` 元素都有闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length

现在已经有了一个 Bootstrap Row，把它分成两列。
|
||||
|
||||
在行内创建两个 class 属性为 `col-xs-6` 的 `div` 元素。
|
||||
|
||||
# --hints--
|
||||
|
||||
两个 `div class="col-xs-6"` 元素应该内嵌入 `div class="row"` 元素中。
|
||||
|
||||
```js
|
||||
assert($('div.row > div.col-xs-6').length > 1);
|
||||
```
|
||||
|
||||
确保所有的 `div` 元素都有闭合标签。
|

code.match(/<\/div>/g) &&
|

code.match(/<div/g) &&

可以在 submit `button` 元素内加上 `<i class="fa fa-paper-plane"></i>`，来添加 Font Awesome 的 `fa-paper-plane` 图标。
|
||||
|
||||
为表单的文本输入框（text input）设置 `form-control` class。 为表单的提交（submit）按钮设置 `btn btn-primary` class， 并为它加上 Font Awesome 的 `fa-paper-plane` 图标。
|
||||
|
||||
所有文本输入类的元素如 `<input>`，`<textarea>` 和 `<select>` 只要设置 `.form-control` class 就会占满100%的宽度。
|
||||
|
||||
# --hints--
|
||||
|
||||
给你的 submit 按钮添加 `btn btn-primary` class。
|
||||
|
||||
```js
|
||||
assert($('button[type="submit"]').hasClass('btn btn-primary'));
|
||||
```
|
||||
|
||||
在你的 submit `button` 元素内添加 `<i class="fa fa-paper-plane"></i>`。
|
||||
|
||||
```js
|
||||
assert($('button[type="submit"]:has(i.fa.fa-paper-plane)').length > 0);
|
||||
```
|
||||
|
||||
给表单中的 text `input` 元素添加 `form-control` class。
|
||||
|
||||
```js
|
||||
assert($('input[type="text"]').hasClass('form-control'));
|
||||
```
|
||||
|
||||
确保每一个 `i` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(code.match(/<\/i>/g) && code.match(/<\/i/g).length > 3);
|
||||

`btn-primary` class 的颜色是应用的主要颜色。 这样 “突出显示” 是引导用户按部就班进行操作的有效办法。
|
||||
|
||||
将按钮的 class 从 Bootstrap 的 `btn-default` 替换为 `btn-primary`。
|
||||
|
||||
注意：按钮仍然需要 `btn` 和 `btn-block` classes。
|
||||
|
||||
# --hints--
|
||||
|
||||
按钮的 class 属性应该包含 `btn-primary`。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn-primary'));
|
||||
```
|
||||
|
||||
按钮的 class 属性应该包含 `btn` 和 `btn-block`。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn-block') && $('button').hasClass('btn'));
|
||||
```
|
||||
|
||||
确保所有 `button` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length

);

title: 使用 span 创建行内元素
|

# --description--
|
||||
|
||||
可以使用 span 标签来创建行内元素。 还记得怎么使用 `btn-block` class 来创建填满整行的按钮吗？
|
||||
|
||||
<button class='btn' style='background-color: rgb(0, 100, 0); color: rgb(255, 255, 255);'>普通按钮</button>
|
||||
|
||||
<button class='btn btn-block' style='background-color: rgb(0, 100, 0); color: rgb(255, 255, 255);'>块级按钮</button>
|
||||
|
||||
上面的例子就是 "inline" （行内）元素和 "block" （块级）元素的区别。
|
||||
|
||||
通过使用行内元素 `span`，可以把不同的元素放在同一行，甚至能为一行的不同部分指定不同样式。
|
||||
|
||||
使用一个 `span` 元素，将文本 `love` 嵌入现在包含文本 `Things cats love` 的 `p` 元素中。 然后给 `span` 元素设置 class `text-danger`，使文本变成红色。
|
||||
|
||||
对含有文本 `Top 3 things cats hate` 的 `p` 元素这样处理：
|
||||
|
||||
```html
|
||||
<p>Top 3 things cats <span class="text-danger">hate:</span></p>
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
`span` 元素应该在 `p` 元素内。
|
||||
|
||||
```js
|
||||
assert($('p span') && $('p span').length > 0);
|
||||
```
|
||||
|
||||
`span` 元素应该有文本 `love`。
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('p span') &&
|
||||
$('p span').text().match(/love/i) &&
|
||||
!$('p span')
|
||||
.text()
|
||||
.match(/Things cats/i)
|
||||
);
|
||||
```
|
||||
|
||||
`span` 元素应该有 `text-danger` class。
|
||||
|
||||
```js
|
||||
assert($('span').hasClass('text-danger'));
|
||||
```
|
||||
|
||||
`span` 元素应该有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/span>/g) &&
|
||||
code.match(/<span/g) &&
|
||||
code.match(/<\/span>/g).length === code.match(/<span/g).length
|
||||
);
|
||||
```

|

使用 jQuery 时，修改 HTML 元素时并不需要直接修改 HTML 代码。
|
||||
|
||||
必须确保让每个人都知道不应该直接修改此页面上的这些代码。
|
||||
|
||||
记住，可以在 `<!--` 为开始，`-->` 为结束的地方进行评论注释。
|
||||
|
||||
请你在 HTML 顶部加如下一段注释： `Code below this line should not be changed` 。
|
||||
|
||||
# --hints--
|
||||
|
||||
应该在 HTML 顶部增加此代码 `<!--` 以开始注释。
|
||||
|
||||
```js
|
||||
assert(code.match(/^\s*<!--/));
|
||||
```
|
||||
|
||||
注释内容应该为 `Code below this line should not be changed`。
|
||||
|
||||
```js
|
||||
assert(code.match(/<!--(?!(>|->|.*-->.*this line))\s*.*this line.*\s*-->/gi));
|
||||
```
|
||||
|
||||
注释应该用 `-->` 进行闭合。
|
||||
|
||||
```js
|
||||
assert(code.match(/-->.*\n+.+/g));
|
||||
```
|
||||
|
||||
注意，注释的开始标签和闭合标签数量应该一一对应，保持数量一致。
|
||||
|
||||
```js
|
||||
assert(code.match(/<!--/g).length === code.match(/-->/g).length);
|
||||
```

title: 使用 Bootstrap Fluid 容器实现响应式设计
|

# --description--
|
||||
|
||||
之前，在 freeCodeCamp 的 HTML5 和 CSS 章节中我们构建了一个 Cat Photo App。 我们在此基础上继续学习。 这次我们将会使用最受欢迎的响应式 CSS 框架 Bootstrap 来美化它。
|
||||
|
||||
Bootstrap 会根据屏幕大小来动态调整 HTML 元素的大小————因此称为 <dfn>Responsive Design</dfn>（响应式设计）。
|
||||
|
||||
通过响应式设计，我们将无需额外设计一个手机版的网页， 因为它在任何尺寸的屏幕上看起来都很棒。
|
||||
|
||||
任何 Web 应用，都可以通过添加如下代码到 HTML 顶部来引入 Bootstrap 。
|
||||
|
||||
```html
|
||||
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"/>
|
||||
```
|
||||
|
||||
不过在这里，已经预先为此页面添加了上述代码。 注意使用 `>` 或者 `/>` 两种方式闭合 `link` 标签都是可行的。
|
||||
|
||||
首先，我们应该将所有 HTML（ `link` 标签和 `style` 元素除外）嵌套在带有 `container-fluid` class 的 `div` 元素里面。
|
||||
|
||||
# --hints--
|
||||
|
||||
`div` 元素应该有 `container-fluid` class。
|
||||
|
||||
```js
|
||||
assert($('div').hasClass('container-fluid'));
|
||||
```
|
||||
|
||||
`div` 元素应该有结束标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length
|
||||
);
|
||||
```
|
||||
|
||||
`style` 结束标签后面的所有 HTML 元素都应该被嵌套在 `.container-fluid` 里面。
|
||||
|
||||
```js
|
||||
assert($('.container-fluid').children().length >= 8 && !$('.container-fluid').has("style").length && !$('.container-fluid').has("link").length);
|
||||
```

# --description--
|
||||
|
||||
Bootstrap 具有一套 12 列的响应式栅格系统，可以轻松的将多个元素放入一行并指定它们的相对宽度。 Bootstrap 的大部分 class 属性都可以应用在 `div` 元素上。
|
||||
|
||||
Bootstrap 的列宽取决于用户的屏幕宽度。 比如，手机有着窄屏幕而笔记本电脑有者更大的屏幕.
|
||||
|
||||
就拿 Bootstrap 的 `col-md-*` class 来说。 在这里， `md` 表示 medium （中等的）， 而 `*` 是一个数字，说明了这个元素占有多少个列宽度。 这个例子就是指定了中等大小屏幕（例如笔记本电脑）下元素所占的列宽度。
|
||||
|
||||
在 Cat Photo App 中，将使用 `col-xs-*` ， 其中 `xs` 是 extra small 的缩写 (比如窄屏手机屏幕)， `*` 是填写的数字，代表一行中的元素该占多少列宽。
|
||||
|
||||
将 `Like`，`Info` 和 `Delete` 三个按钮并排放入一个 `<div class="row">` 元素中，然后每个按钮都各用一个 `<div class="col-xs-4">` 元素包裹起来。
|
||||
|
||||
当 `div` 元素设置了 `row` class 之后，那几个按钮便会嵌入其中了。
|
||||
|
||||
# --hints--
|
||||
|
||||
所有按钮都需要嵌入到同一个 `div` 元素中， 并且该元素包含 `row` class 属性。
|
||||
|
||||
```js
|
||||
assert($('div.row:has(button)').length > 0);
|
||||
```
|
||||
|
||||
每个 Bootstrap 按钮都需要嵌入各自的 `div` 元素，并且该元素包含 class 属性 `col-xs-4`。
|
||||
|
||||
```js
|
||||
assert($('div.col-xs-4:has(button)').length > 2);
|
||||
```
|
||||
|
||||
确保每一个 `button` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||||
);
|
||||
```
|
||||
|
||||
确保每一个 `div` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/div>/g) &&
|
||||
code.match(/<div/g) &&
|
||||
code.match(/<\/div>/g).length === code.match(/<div/g).length
|
||||
);
|
||||
```

|

Bootstrap 有着丰富的预定义按钮颜色。 红色 `btn-danger` class 用来提醒用户此行为具有破坏性，比如删除一张猫的图片。
|
||||
|
||||
创建一个带有文本 `Delete` 的按钮，给它设置 class `btn-danger`。
|
||||
|
||||
注意：这些按钮仍然需要 `btn` 和 `btn-block` class。
|
||||
|
||||
# --hints--
|
||||
|
||||
应创建一个新的带有文本 `Delete` 的 `button` 元素。
|
||||
|
||||
```js
|
||||
assert(new RegExp('Delete', 'gi').test($('button').text()));
|
||||
```
|
||||
|
||||
所有 Bootstrap 按钮的 class 属性都应该包含 `btn` 和 `btn-block`。
|
||||
|
||||
```js
|
||||
assert($('button.btn-block.btn').length > 2);
|
||||
```
|
||||
|
||||
新创建按钮的 class 属性应该包含 `btn-danger`。
|
||||
|
||||
```js
|
||||
assert($('button').hasClass('btn-danger'));
|
||||
```
|
||||
|
||||
确保所有的 `button` 元素都有一个闭合标签。
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/button>/g) &&
|
||||
code.match(/<button/g) &&
|
||||
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||||
);
|
