Question

我现在尝试跳转介绍CSS网格！但有一件事对我来说并不清楚。你将如何建立一个主网格/布局，你的标题，英雄和页脚背景颜色可能有完整的浏览器宽度（如stackoverflow页眉/页脚）？没有嵌套div，就像你今天使用flexbox，floats＆amp;合。这可能是干净的吗？我希望你明白我努力工作。我添加了一个图像，也许这使得它更清晰;）

好的，这是一个小提琴：

但是现在我希望topbar，hero和footer的背景颜色是完整的浏览器大小，而不需要使用我的区域周围的经典嵌套div。如果我必须这样做，我看不到css网格对整体布局的任何好处。

您可以做的是使用容器创建某个HTML布局，该容器会强制某些元素保持在设定的宽度范围内。然后容器外的任何东西都将显示为全宽。

这是一个实时的JSFiddle example。

<强> HTML

<div class="wrapper">
    <div class="section">
        <div class="container">
            <!-- Set width content -->
        </div>
    </div>
    <div class="section">
        <div class="container">
            <!-- Set width content -->
        </div>
    </div>
    <div class="section">
        <!-- Full width content -->
    </div>
</div>

<强> CSS

.wrapper {
  width: 100%;
  height: 100%;
}

.container {
  width: 80%;
  margin: 0 auto;
}

具有完整浏览器宽度背景颜色的CSS Grid Item？
