CSS Grid layout (Grid) can divide web pages into rows and columns with simple attributes. You can directly use CSS to position and adjust each element in the grid, and there is no need to perform multi-layer embedding in order to achieve a certain layout. Set, in short, css grid layout is very easy to use. Let’s take a look at the content of css grid layout described in this article.
CSS Grid layout consists of two core components: parent element and child element. The parent element is the actual grid (grid). Child elements are the content within the grid.
The following is a parent element and six child elements
<div> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>5</div> <div>6</div> </div>
To turn the parent element into a grid (grid), simply set its display attribute to grid
Effect Picture:
The following is the grid layout:
.box { width: 350px; height: 350px; /* background: #ccc; */ margin: 0 auto; grid-gap: 5px; display: grid; grid-template-columns: 100px 100px 100px; grid-template-rows: 100px 100px 100px; } .item { border: 1px solid black; box-sizing: border-box; } .div1 { grid-column-start: 1; grid-column-end: 3; /*(div1从占据从第一条网格线开始,到第三条网格线结束)*/ line-height: 100px; text-align: center; background: rgb(252, 0, 0); /* grid-column: 1/3;(这是缩写的形式) */ } .div2 { line-height: 100px; text-align: center; background: rgb(252, 134, 0); } .div3 { grid-row-start: 2; grid-row-end: 4; /* grid-row: 2/4;(这是缩写的形式) */ line-height: 200px; text-align: center; background: rgb(21, 207, 108); } .div4 { grid-column-start: 2; grid-column-end: 4; line-height: 100px; text-align: center; background: rgb(18, 21, 189); /* grid-column: 2/4;(这是缩写的形式) */ } .div5 { line-height: 100px; text-align: center; background: rgb(16, 170, 197); } .div6 { line-height: 100px; text-align: center; background: rgb(172, 126, 199); }
The grid lines in the above code (arrows in the figure) The place pointed to is a grid line):
2. Responsive grid layout
Similar to the above (with the following content added)
Use the grid-template-columns property to create a 12-column grid, each column is a unit width (1/12 of the total width)
Create 3 rows using the grid-template-rows property
Use the grid-gap property to add a gap between grid items in the grid.
The code is as follows:
<div class="container"> <div class="header">顶部(一个点表示一个空白的格子),所以距离左边和右边各有一个格子的距离。</div> <div class="menu">中间1</div> <div class="content">中间2所以可以利用空白的格子来对你所要拍的网页来进行布局</div> <div class="footer">底部(一个点表示一个空白的格子),所以距离右边有三个格子的距离。</div> </div>
Add grid-template-areas
This attribute is called the grid area, also called the template area, which allows us to easily conduct layout experiments.
Rendering:
.container { display: grid; grid-template-columns: repeat(12, 1fr); grid-template-rows: 50px 350px 50px; grid-gap: 5px; grid-template-areas: ". h h h h h h h h h h ." " m m c c c c c c c c c c" "f f f f f f f f f . . ."; } .container>p { border: 1px solid #ccc; box-sizing: border-box; } .header { text-align: center; line-height:50px; grid-area: h; color:rgb(219, 52, 169); } .menu { grid-area: m; text-align: center; line-height:350px; } .content { text-align: center; line-height:350px; grid-area: c; color:rgb(25, 158, 69); } .footer { color:rgb(212, 112, 18); text-align: center; line-height:50px; grid-area: f; }Recommended related articles:
