# --description--

|
D3 可以使用 `style()` 方法为动态元素添加内联 CSS 样式表。
|
|
|
|
`style()` 方法以用逗号分隔的键值对作为参数。这里是一个将选中文本的颜色设为蓝色的例子：
|
|
|
|
`selection.style("color","blue");`
|
|
|
|
# --instructions--
|
|
|
|
在编辑器中添加 `style()` 方法，使所有显示的文本的 `font-family` 为 `verdana`。
|
|
|
|
# --hints--
|
|
|
|
你的 `h2` 元素的 `font-family` 应该为 verdana。
|
|
|
|
```js
|
|
assert($('h2').css('font-family') == 'verdana');
|
|
```
|
|
|
|
你应该使用 `style()` 方法。
|
|
|
|
```js
|
|
assert(code.match(/\.style/g));
|
|
```
|

d3.select("body").selectAll("h2")
|

.data(dataset)
|

.enter()
|

.append("h2")
|

.text((d) => (d + " USD"))
