## Description
 | 
						||
<section id="description">有时您希望CSS Grid中的所有项目共享相同的对齐方式。您可以使用以前学过的属性并单独对齐它们,也可以使用网格容器上的<code>justify-items</code>将它们全部水平<code>justify-items</code> 。此属性可以接受您在前两个挑战中学到的所有相同值,不同之处在于它会将网格中的<b>所有</b>项目移动到所需的对齐方式。 </section>
 | 
						||
 | 
						||
## Instructions

						||
<section id="instructions">使用此属性可以水平居中所有项目。 </section>

  - text: <code>container</code>类应该有一个具有<code>center</code>值的<code>justify-items</code>属性。
 | 
						||
    testString: 'assert(code.match(/.container\s*?{[\s\S]*justify-items\s*?:\s*?center\s*?;[\s\S]*}/gi), "<code>container</code> class should have a <code>justify-items</code> property that has the value of <code>center</code>.");'
