This article brings you an introduction to the usage of the grid attribute in CSS (code). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
grid layout
Attributes added to the parent element
grid-template-columns/grid-template-rows
Defines the width and height of the row or column of the element
If the parent element is divided into 9 equal parts, no matter how many children there are Elements are displayed in 9 equal parts
grid-template-columns: 33% 33% 33%; can be written as grid-template-columns:repeat(3, 33%);
.container { width: 200px; height: 200px; display: grid; background-color: coral; margin: 10px; } .container .item { border: 1px solid #ccc; background-color: chocolate; } .container1 { grid-template-columns: 33% 33% 33%; grid-template-rows: 33% 33% 33%; }
<div> <div></div> <div></div> </div>
grid-template-areas
Parent The grid-template-areas of the element cooperates with the grid-area of the child element to define the grid area
A period represents an empty grid unit
.container { width: 200px; height: 200px; display: grid; background-color: coral; margin: 10px; } .container .item { border: 1px solid #ccc; background-color: chocolate; } .container2 { grid-template-columns: 1fr 1fr 1fr 1fr; grid-template-rows: 1fr 1fr 1fr; grid-template-areas: "header header . footer" "main main . sidebar" "main main . sidebar"; } .container2 .item-1 { grid-area: header; } .container2 .item-2 { grid-area: main; } .container2 .item-3 { grid-area: sidebar; } .container2 .item-4 { grid-area: footer; }
<div> <div>header</div> <div>main</div> <div>sidebar</div> <div>footer</div> </div>
##grid-column-gap/grid-row-gap/grip-gap
.container { width: 200px; height: 200px; display: grid; background-color: coral; margin: 10px; } .container .item { border: 1px solid #ccc; background-color: chocolate; } .container3 { grid-template-columns: repeat(3, 30%); grid-template-rows: repeat(3, 30%); grid-column-gap: 2%; grid-row-gap: 2%; }
<div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> </div>
