## Description
|
|||
|
|
<section id="description">在CSS Grid中，每个项目的内容位于一个称为<dfn>单元格</dfn>的框中。您可以使用网格项上的<code>justify-self</code>属性水平对齐内容在其单元格中的位置。默认情况下，此属性的值为<code>stretch</code> ，这将使内容填充单元格的整个宽度。此CSS Grid属性也接受其他值： <code>start</code> ：对齐单元格左侧的内容， <code>center</code> ：对齐单元格<code>center</code>的内容， <code>end</code> ：对齐单元格右侧的内容。 </section>
