修复了CSS Grid中的标题

标签： html css css3 css-position css-grid

我刚开始摆弄CSS网格，我对如何创建固定标头感到好奇。我应该创建一个两行网格，其中第一行是标题，第二行是内容的另一个网格吗？或者有更简单的方法来解决这个问题吗？

我已经为网格中的div添加了高度以启用滚动。

提前谢谢你。这是我为测试设置的HTML / CSS：

在2018年，您可以使用position: sticky 

header {
  position: sticky;
  top: 0;
}

Here is a JSFiddle对其进行演示。

Browser support-适用于header元素（已在Chrome和Edge中测试）。

将网格容器的子项设置为position: fixed后，它将从文档流中删除，不再参与网格布局（see section 9.2 of the grid spec）。

因此，如果要将元素固定到视口，则从网格容器中删除元素是有意义的。如果它是标题，只需将其放在网格容器上方。

如果你仍然希望标题是一个没有问题的网格。固定元素可以是网格容器。他们只是作为网格项目做得不好。

诀窍是创建一个父内容容器，其溢出设置为 auto 和 固定高度（触发溢出），然后将您的内容添加为它的子项。

body {
  margin: 0;
}

.page {
  display: grid;
  grid-template-rows: 55px calc(100vh - 55px); /* height limitation on second row */
  grid-template-areas: "header" 
                       "content";
}

.header {
  grid-area: header;
  background-color: darkgray;
}

.content {
  grid-area: content;
  background-color: grey;
  overflow: auto;  /* overflow condition on parent */
}

article {
  height: 500px;  /* height set on child; triggers scroll */
}
<div class='page'>
    <div class='header'>Header</div>
    <div class='content'>
        <article>
            <h1>title</h1>
        </article>
        <article>
            <h1>title</h1>
        </article>

对于.wrapper {margin-top; 80px; position:relative;}和.header {position:fixed; height: 80px; z-index: 10;}，.wrapper中的网格定义将在固定标题下流动。为了达到良好的效果，请将.header的规则集放在.wrapper之前的顶部。

/* Globals */

body {
  color: white;
}


/* Grid Layout - Not necessarily display:inline-grid; */

.header {
  top: 0px;
  height: 80px;
  background-color: black;
  position: fixed;
  left: 2vw;
  right: 2vw;
  z-index: 10;
  overflow: hidden;
  }

.wrapper {
  position: relative;
  left: 10vw;
  width: 80vw;
  top: 20px;
  margin-top: 80px;
  display: -ms-inline-grid;
  display: -moz-inline-grid;
  display: inline-grid;
  grid-template-columns: repeat(12, [col-start] 1fr);
  grid-template-rows: 1fr; 
  overflow: auto;
}

.jumbotron {
  grid-column: col-start / span 12;
  height: 30vh;
  background-color: yellow;
}

.content-one-left {
  grid-column: col-start / span 6;
  height: 30vh;
  background-color: red;
}

.content-one-right {
  grid-column: col-start 7 / span 6;
  height: 30vh;
  background-color: blue;
}

.content-two-left {
  grid-column: col-start / span 6;
  height: 30vh;
  background-color: blue;
}

.content-two-right {
  grid-column: col-start 7 / span 6;
  height: 30vh;
  background-color: red;
}

.footer {
  grid-column: col-start / span 12;
  height: 10vh;
  background-color: black;
}
<div class="header">
  <p> Header </p>
</div>

<div class="wrapper">



  <div class="jumbotron">
    <p> Jumbotron </p>
  </div>

  <div class="content-one-left">
    <p> Content 1 Left </p>
  </div>

  <div class="content-one-right">
    <p> Content 1 Right </p>
  </div>

  <div class="content-two-left">
    <p> Content 2 Left </p>
  </div>

答案 4 :(得分：0)

.header-container {
    position: sticky;
    position: -webkit-sticky; /* For macOS/iOS Safari */
    top : 0;
}

答案 5 :(得分：-1)

.header{
    position: fixed;
    left:0;
    right:0;
    top:0;
}

使用针对标题固定的位置，它肯定会有效。
