# --description--
|
|
|
|
CSS 里的 `text-transform` 属性可以改变英文字母的大小写。使用这个属性时，我们无需改变 HTML 元素中的文本也可以统一页面里英文的显示。
|
|
|
|
下面的表格展示了 `text-transform` 的不同值对文字 “Transform me” 的影响：
|
|
|
|
<table class='table table-striped'><thead><tr><th>Value</th><th>Result</th></tr></thead><tbody><tr><td><code>lowercase</code></td><td>"transform me"</td></tr><tr><td><code>uppercase</code></td><td>"TRANSFORM ME"</td></tr><tr><td><code>capitalize</code></td><td>"Transform Me"</td></tr><tr><td><code>initial</code></td><td>使用默认值</td></tr><tr><td><code>inherit</code></td><td>使用父元素的 <code>text-transform</code> 值。</td></tr><tr><td><code>none</code></td><td><strong>Default:</strong>不改变文字。</td></tr></tbody></table>
|
|

|
# --instructions--
|
|
|
|
请使用 `text-transform` 属性把 `h4` 内容文本中的所有字母变成大写。
|
|
|
|
# --hints--
|
|
|
|
`h4` 内容文本中，所有字母均应为大写。
|
|
|
|
```js
|
|
assert($('h4').css('text-transform') === 'uppercase');
|
|
```
|
|
|
|
`h4` 内的原文不应改变。
|
|
|
|
```js
|
|
assert($('h4').text() !== $('h4').text().toUpperCase());
|
|
```
