localeTitle: 使用 justify-self 水平对齐项目
|
||
---
|
||
|
||
## Description
|
||
<section id='description'>
|
||
在 CSS 网格中，每个网格项的内容分别位于被称为<dfn>单元格（cell）</dfn>的框内。你可以使用网格项的<code>justify-self</code>属性，设置其内容的位置在单元格内沿行轴对齐的方式。默认情况下，这个属性的值是<code>stretch</code>，这将使内容占满整个单元格的宽度。该 CSS 网格属性也可以使用其他的值：
|
||
<code>start</code>：使内容在单元格左侧对齐，
|
||
<code>center</code>：使内容在单元格居中对齐，
|
||
<code>end</code>：使内容在单元格右侧对齐，
|
||
</section>
|
||
|
||
## Instructions
|
||
<section id='instructions'>
|
||
使用<code>justify-self</code>属性让类为<code>item2</code>的网格项居中。
