两栏布局
要求：一边宽度自适应，另一边固定宽度
两栏布局实现方法有很多，这里总结几种我常用的方法
1.浮动定位+margin实现
左侧固定宽 并浮动，右侧用margin-left或padding-left隔开
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
*{
margin: 0;
padding: 0;
font-size: 24px;
}
.left{
width: 150px;
height: 800px;
background-color: #51eaea;
float: left;
}
.right{
height: 800px;
background-color: #ffdbc5;
margin-left: 160px;
}
</style>
</head>
<body>
<div class="left">固定宽区域</div>
<div class="right">自适应区域</div>
</body>
</html>
2.浮动+开启BFC
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
*{
margin: 0;
padding: 0;
font-size: 24px;
}
.left{
width: 150px;
height: 800px;
background-color: #51eaea;
float: left;
}
.right{
height: 800px;
background-color: #ffdbc5;
overflow: hidden;/*开启BFC或用display: flex*/
}
</style>
</head>
<body>
<div class="left">固定宽区域</div>
<div class="right">自适应区域</div>
</body>
</html>
3.绝对定位+margin实现
与浮动类似
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
*{
margin: 0;
padding: 0;
font-size: 24px;
}
.left{
width: 150px;
height: 800px;
background-color: #51eaea;
position: absolute;
}
.right{
height: 800px;
background-color: #ffdbc5;
margin-left: 160px;
}
</style>
</head>
<body>
<div class="left">固定宽区域</div>
<div class="right">自适应区域</div>
</body>
</html>
4.flex弹性盒子布局(css3)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style>
*{
margin: 0;
padding: 0;
font-size: 24px;
}
.wrap{
display: flex;
}
.left{
width: 150px;
height: 800px;
background-color: #51eaea;
}
.right{
height: 800px;
background-color: #ffdbc5;
flex-grow: 1;/*让第二个盒子铺满剩余空间*/
}
</style>
</head>
<body>
<div class="wrap">
<div class="left">固定宽区域</div>
<div class="right">自适应区域</div>
</div>
</body>
</html>
