## Description
|
|||
|
|
<section id="description">还有另一个内置函数可用于<code>grid-template-columns</code>和<code>grid-template-rows</code>称为<code>minmax</code> 。当网格容器改变大小时，它用于限制项目的大小。为此，您需要指定项目的可接受尺寸范围。这是一个例子： <blockquote> grid-template-columns：100px minmax（50px，200px）; </blockquote>在上面的代码中， <code>grid-template-columns</code>设置为创建两列;第一个是100px宽，第二个是最小宽度50px，最大宽度是200px。 </section>
|
|||
|
|
|
|||
|
|
## Instructions
|
|||
|
|
<section id="instructions">使用<code>minmax</code>函数，将<code>repeat</code>函数中的<code>1fr</code>替换为最小宽度为<code>90px</code>且最大宽度为<code>1fr</code>的列大小，并调整预览面板的大小以查看效果。 </section>
