# --description--
|
||
|
||
D3 可以将样式添加到条形标签中。 `fill` 属性为 `text` 节点设置文本颜色， `style()` 方法设置其它样式的 CSS 规则，例如 `font-family` 或 `font-size`。
|
||
|
||
# --instructions--
|
||
|
||
将 `text` 元素的 `font-size` 设置为 `25px`，文本颜色设置为红色（red）。
|
||
|
||
# --hints--
|
||
|
||
所有标签的 `fill` 颜色应该是 red。
|
||
|
||
```js
|
||
assert($('text').css('fill') == 'rgb(255, 0, 0)');
|
||
```
|
||
|
||
所有标签的 `font-size` 应为 `25` 像素。
|
||
|
||
```js
|
||
assert($('text').css('font-size') == '25px');
|
||
```
