Question

我试图了解HTML结构如何影响CSS Grid Layout Module规范。我使用Chrome Canary启用了实验性功能。

附加的代码按预期工作，但是仅仅为了语义而将导航和搜索放在头标记内部会抛出CSS网格放置。

我缺少什么能够使用CSS网格模块并仍然保留我的标题标签中包含导航，品牌和搜索的语义标题？

Answer 1

想出来，如果你在标题中放置品牌，导航和搜索它们不再是网格的直接后代，那么要正确放置它们，你需要在{{1时创建另一个网格/子网格}}关键字可用。现在，您可以使用display：grid with related dimensions

鉴于此HTML：

subgrid

CSS将是：

<div class="wrapper">
<div class="header">
    <h1 class="logo">Simply Expense</h1>
    <nav class="navbar">
        <ul>
            <li><a href="#">Expenses</a></li>
            <li><a href="#">Receipts</a></li>
            <li><a href="#">Reports</a></li>
        </ul>
    </nav>
    <div class="search">
        <button>test</button>
        <input type="text">
    </div>
</div>
</div>

为什么我的HTML结构不能与CSS Grid布局一起使用？
