Question

我正在尝试创建一个相当简单的网站布局，但是对于CSS Grid来说，这是我的新手，我敢肯定我会以错误的方式进行操作。

body{
    margin: 0;
    padding: 0;
}

.container {
    display: grid;
    grid-template-columns: 1fr 3fr 1fr;
    grid-template-rows: 120px 450px;
}

.header,
.main {
    border: 1px solid black;
}

.side {
    background-color: antiquewhite;
    border-bottom: 1px solid black;
}

<div class="container">
  <div class="side">Should have the same background color/gradient as header</div>
  <header class="header">Header</header>
  <div class="side">Should have the same background color/gradient as header</div>
  <div class="side">Should have the same background color/gradient as Content</div>
  <main class="main">Content</main>
  <div class="side">Should have the same background color/gradient as Content</div>
</div>

这就是我想要的：一个标题和一个主要部分，两者的内容都保留在页面的中心-但同时我希望这两行的整体都有自己的背景颜色。但是我的解决方案使用了一堆不必要的div，并且grid-template-rows: 150px 450px;的使用也是错误的，因为我希望内容占据页面的其余部分而不是450px。

我该如何实现？

Answer 1

尝试为容器类提供最大宽度和边距

 .container{
     max-width:calc( (3/5) * 100vw);
     margin:0 auto; 
     grid-template-rows: 120px 1fr; 
     display:grid;
  }

您可以这样简化：

body {
  margin: 0;
  padding: 0;
  display: grid;
  grid-template-columns: 1fr 3fr 1fr;
  min-height:100vh;
  background:
    linear-gradient(red, blue) top/100% 120px no-repeat,
    linear-gradient(green, grey) bottom/100% calc(100% - 120px) no-repeat;
}
body:before,
body:after{
  content:"";
}

.container {
  display: grid;
  grid-template-rows: 120px 1fr;

}

.header,
.main {
  border: 1px solid black;
}

<div class="container">
  <header class="header">Header</header>
  <main class="main">Content</main>
</div>

如果这是您体内唯一的内容，则还可以使用max-width和vw单位，如下所示：

body {
  margin: 0;
  padding: 0;
  background:
    linear-gradient(red, blue) top/100% 120px no-repeat, /*Cover the header*/
    linear-gradient(green, grey) bottom/100% calc(100% - 120px) no-repeat; /*Cover the content*/
}
.container {
  /* you want 1f 3fr 1fr so we have 5fr so we need (3/5)*/
  max-width:calc( (3/5) * 100vw);
  margin:auto;
  display: grid;
  grid-template-rows: 120px 1fr;
  min-height:100vh;
}

.header,
.main {
  border: 1px solid black;
}

<div class="container">
  <header class="header">Header</header>
  <main class="main">Content</main>
</div>

尝试这个：

body {
  margin: 0;
  padding: 0;
}

div.container {
  display: grid;
  grid-template-columns: 1fr 3fr 1fr;
  grid-template-rows: 150px; 1fr;
  height: 100vh;
}

.header-container, .content-container {
  display: contents;
}

.header-container div {
  background: #ddd;
}

.content-container div {
  background: #aaa;
}

<body>
  <div class="container">
    <div class='header-container'>
      <div class='side'>Side</div>
      <div class='header'>Header</div>
      <div class='side'>Side</div>
    </div>
    <div class='content-container'>
      <div class='side'>Side</div>
      <div class='content'>Content</div>
      <div class='side'>Side</div>
    </div>
  </div>
</body>
