| # --description--
 | ||
| 
 | ||
| 之前,在 freeCodeCamp 的 HTML5 和 CSS 章節中我們構建了一個 Cat Photo App。 我們在此基礎上繼續學習。 這次我們將會使用最受歡迎的響應式 CSS 框架 Bootstrap 來美化它。
 | ||
| 
 | ||
| Bootstrap 會根據屏幕大小來動態調整 HTML 元素的大小————因此稱爲 <dfn>Responsive Design</dfn>(響應式設計)。
 | ||
| 
 | ||
| 通過響應式設計,我們將無需額外設計一個手機版的網頁, 因爲它在任何尺寸的屏幕上看起來都很棒。
 | ||
| 
 | ||
| 任何 Web 應用,都可以通過添加如下代碼到 HTML 頂部來引入 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"/>
 | ||
| ```
 | ||
| 
 | ||
| 不過在這裏,已經預先爲此頁面添加了上述代碼。 注意使用 `>` 或者 `/>` 兩種方式閉合 `link` 標籤都是可行的。
 | ||
| 
 | ||
| 首先,我們應該將所有 HTML( `link` 標籤和 `style` 元素除外)嵌套在帶有 `container-fluid` class 的 `div` 元素裏面。
 | ||
| 
 | ||
| # --hints--
 | ||
| 
 | ||
| `div` 元素應該有 `container-fluid` class。
 | ||
| 
 | ||
| ```js
 | ||
| assert($('div').hasClass('container-fluid'));
 | ||
| ```
 | ||
| 
 | ||
| `div` 元素應該有結束標籤。
 | ||
| 
 | ||
| ```js
 | ||
| assert(
 | ||
|   code.match(/<\/div>/g) &&
 | ||
|     code.match(/<div/g) &&
 | ||
|     code.match(/<\/div>/g).length === code.match(/<div/g).length
 | ||
| );
 | ||
| ```
 | ||
| 
 | ||
| `style` 結束標籤後面的所有 HTML 元素都應該被嵌套在 `.container-fluid` 裏面。
 | ||
| 
 | ||
| ```js
 | ||
| assert($('.container-fluid').children().length >= 8 && !$('.container-fluid').has("style").length && !$('.container-fluid').has("link").length);
 | ||
| ```
