<p><strong>网格区域</strong>是网格中由一个或者多个{{glossary("grid cell", "网格单元格")}}组成的一个矩形区域。当你使用<a href="/en-US/docs/Web/CSS/CSS_Grid_Layout/Line-based_Placement_with_CSS_Grid">基于网格线位置</a>放置一个项目或者使用<a href="/en-US/docs/Web/CSS/CSS_Grid_Layout/Grid_Template_Areas">命名的网格区域</a>定义区域时，网格区域被创建。</p>

<p><img alt="Image showing a highlighted grid area" src="https://mdn.mozillademos.org/files/14771/1_Grid_Area.png" style="height: 253px; width: 380px;"></p>

<p>本质上，网格区域一定是矩形的。例如，不可能创建T形或L形的网格区域。</p>

<p>在下面的例子中，有一个网格容器包含两个网格项目，我用 {{cssxref("grid-area")}} 属性命名它们，然后用 {{cssxref("grid-template-areas")}} 把它们放在网格上。这将创建两个网格区域，一个覆盖四个网格单元格，另外一个覆盖两个。</p>

<div id="example_1">
<div class="hidden">

.wrapper {

    background-color: #fff4e6;
