浮动布局
分为三个div,另外一个父级包含这三个div,使用float,
注意点:三个div,left --> right ---> center 这种顺序
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style type="text/css">
body {
margin: 0;
padding: 0;
}
.left {
float: left;
width: 300px;
height: 100px;
background-color: red;
}
.right {
float: right;
width: 300px;
height: 100px;
background-color: blue;
}
.center {
margin: 0px 300px 0px 300px;
background-color: black;
height: 100px;
}
</style>
</head>
<body>
<div class="father">
<div class="left">1</div>
<div class="right">2</div>
<div class="center">3</div>
</div>
</body>
</html> Flex
设置中间盒子FLex:1,这样的话就可以实现自适应,默认水平排列
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style type="text/css">
.father {
display: flex;
}
.left {
width: 300px;
height: 100px;
background-color: red;
}
.center {
flex:1;
height: 100px;
background-color: black;
}
.right {
width: 300px;
height: 100px;
background-color: blue;
}
</style>
</head>
<body>
<div class="father">
<div class="left"></div>
<div class="center"></div>
<div class="right"></div>
</div>
</body>
</html>flex相关知识点,一般会使用到的
1、设置display:flex
2、容器图:
轴:水平main axis和垂直cross axis
3、容器的属性
flex-direction:主轴的方向,row | row-reverse | column | column-reverse;
flex-wrap:换行, nowrap | wrap | wrap-reverse;
flex-flow:flex-direction和flex-wrap简写
justify-content:主轴上的对齐方式, flex-start | flex-end | center | space-between | space-around;
align-items:交叉轴上如何对齐,flex-start | flex-end | center | baseline | stretch;
绝对定位对齐
