网格单元的对齐方式

只有项目在网格单元中存在剩余空间时,对齐才有意义;
1、设置所有项目的对齐方式
书写在容器中:place-items: 垂直方向 水平方向;
方位词start end center
垂直居上,水平居中:place-items: start center;
水平垂直居中:place-items: center;
normal->auto同义词
inherit:继承默认值
initial:初始化
unset:在继承和初始化之间切换
默认是拉伸:stretch 没有固定尺寸才有效果
2、设置容器中某一个项目在网格单元中的对齐方式
书写在项目中:place-self:垂直方向 水平方向;
同1中的用法一样

网格容器的对齐方式

书写在容器中place-content:垂直方向 水平方向;
1、将所有项目作为一个整体在容器中对齐
place-content:start start;默认
place-content: center;
2、将所有项目打散成独立个体在容器中设置对齐方式
place-content: space-between;俩端对齐
place-content: space-around ;分散对齐
place-content: space-evenly;平均对齐

使用命名网格区域实现圣杯布局

grid-area可以命名网格区域
效果图

  1. <style>
  2. body {
  3. display: grid;
  4. grid-template-columns: 15em minmax(50vh, auto) 15em;
  5. grid-template-rows: 3em minmax(80vh, auto) 3em;
  6. gap: .5em;
  7. grid-template-areas: 'header header header' 'left main right' 'footer footer foot';
  8. grid-template-areas: 'header header header' '. main .' 'footer footer foot';
  9. }
  10. body * {
  11. border: 1px solid #ccc;
  12. }
  13. header {
  14. grid-area: header;
  15. }
  16. footer {
  17. grid-area: footer;
  18. }
  19. /* aside.left {
  20. grid-area: left;
  21. }
  22. aside.right {
  23. grid-area: right;
  24. } */
  25. main {
  26. grid-area: main;
  27. }
  28. </style>
  29. <body>
  30. <header>header</header>
  31. <main>main</main>
  32. <aside class="left">left</aside>
  33. <aside class="right">right</aside>
  34. <footer>footer</footer>
  35. </body>

使用grid模拟栅格

grid实现媒体查询

根据自动填充,根据当前宽度自动决定放几行几列;
auto-fit auto-fill

  1. grid-template-columns: repeat(auto-fit,minmax(15em,1fr));
  2. grid-template-rows: repeat(auto-fit,minmax(13em,70%));
