在css网格上的粘性标题

Question

我有一个漂亮的响应css模板使用CSS网格,我想使这个响应css网格的标题粘,但由于标题和导航设计的方式,我不能让它使用固定定位.

有没有一种更好的方法来实现这一点,我可能还没有看过一些网格属性？

* {
  margin: 0;
  padding: 0;
}

body {
  display: grid;
  font-family: sans-serif;
}

a {
  text-decoration: none;
  color: white;
}

header,
nav {
  background: blue;
  color: #fff;
  position: fixed;
}

nav {
  display: flex;
  flex-wrap: wrap;
  align-items: center;
}

nav span {
  margin-right: auto;
}

header {
  display: none;
}

aside {
  background: lightgreen;
}

main {
  background: pink;
}


/* mobile  */

@media (max-width: 767px) {
  body {
    grid-template-columns: 1fr;
    grid-template-rows: 1fr 1fr 1fr;
  }
  nav,
  aside,
  main {
    grid-column: 1 / 1;
    padding: 0 15px;
  }
}


/* tablets */

@media (min-width: 768px) {
  body {
    grid-template-columns: 275px 1fr;
    grid-template-rows: 1fr 1fr;
  }
  nav {
    grid-column: 1 / 4;
    grid-row: 1;
    height: 50px;
    grid-row: 1;
  }
  aside {
    grid-column: 1;
  }
  main {
    grid-column: 2;
  }
  nav,
  aside,
  main {
    padding: 0 15px;
  }
}


/* desktops */

@media (min-width: 992px) {
  body {
    grid-template-columns: 10% 275px 1fr 10%;
    grid-template-rows: 1fr 1fr;
  }
  header {
    display: block;
    grid-column: 1 / -1;
    grid-row: 1;
  }
  nav {
    grid-column: 2 / 4;
    grid-row: 1;
  }
  aside {
    grid-column: 2 / 3;
  }
  main {
    grid-column: 3 / 4;
  }
}


/* xl desktops */

@media (min-width: 1920px) {
  body {
    grid-template-columns: 1fr minmax(auto, 300px) minmax(auto, 1620px) 1fr;
    grid-template-rows: 1fr 1fr;
  }
}

Answer 1

使用position: fixed;将把它从流程中取出,因此不会成为网格系统的一部分.要做到这一点,你可以使用非标准position: sticky;用top: 0;,回退是它表现得像非粘性元素.

在这里,我假设nav元素是你的标题,因为你header设置为display: none;但position属性可以移动到网格的任何元素(header如果你不打算显示它,为什么要放入你的标记？)

  margin: 0;
  padding: 0;
}

body {
  display: grid;
  font-family: sans-serif;
}

a {
  text-decoration: none;
  color: white;
}

header,
nav {
  background: blue;
  color: #fff;
  position: fixed;
}

nav {
  position: -webkit-sticky;
  position: sticky;
  top: 0;
  display: flex;
  flex-wrap: wrap;
  align-items: center;
}

nav span {
  margin-right: auto;
}

header {
  display: none;
}

aside {
  background: lightgreen;
}

main {
  background: pink;
}

  nav,
  aside,
  main {
    grid-column: 1 / 1;
    padding: 0 15px;
  }
}

    grid-column: 1 / 4;
    grid-row: 1;
    height: 50px;
    grid-row: 1;
  }
