This article will introduce to you three common CSS page layouts: double flying wing layout, adhesion layout, and left and right column layout. I hope it will be of some help to you.
(Recommended tutorial: CSS video tutorial)
1. Left and right column layout
1. The code is as follows
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>两列布局</title>
<!--左边列固定，右边列自适应-->
<style type="text/css">
*{
padding: 0;
margin: 0;
}
body{
min-width: 600px;
}
.lef{
width: 100px;
height: 400px;
background: hotpink;
float: left;
}
.rig{
height: 400px;
background: yellowgreen;
margin-left: 50px;
/*给right开启BFC
利用BFC的特性：
bfc的区域不会与浮动的box重叠*/
/* 溢出内容部分被切割,所以使用省略号表示 */
overflow: hidden;
/*出现省略号需要四个设置：
* display: block;
* overflow: hidden;
* white-space: nowrap;
* text-overflow: ellipsis
* */
/* white-space: nowrap; */
/* text-overflow: ellipsis; */
}
.con{
width: 300px;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="con">
<div class="lef">left</div>
<div class="rig">
lzprightrightrightrightrightrightrightrightrightrightrightrightrightright <br />
rightrightrightrightrightrightrightrightrightrightrightrightrightright <br />
rightrightrightrightrightrightrightrightrightrightrightrightrightright <br />
rightrightrightrightrightrightrightrightrightrightrightrightrightright <br />
</div>
</div>
</body>
</html>The effect is as follows:
2. Necessary instructions
The outer container con if For a fixed width, the overflow: hidden; of the right element is necessary, otherwise the font in the rig will not be in the rig.
If the con width of the outer container is 100%, or the default, the overflow: hidden; of the right element is optional, and the page will not be affected.
2. Adhesion layout
1. The code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,user-scalable=no,maximum-scale=1.0,minimum-scale=1.0"/>
<title>粘连布局</title>
<!--
当页面中无内容或内容不足一屏时，footer在页面最底部显示
当页面内容很多一屏装不下时，footer紧随内容其后显示
-->
<style type="text/css">
*{
padding: 0;
margin: 0;
}
html, body{
height: 100%;
}
.wrap{
/* 设置wrap的最小高度,当main元素中的内容较少或者为空时，也能保持100%高度 */
min-height: 100%;
background: yellowgreen;
text-align: center;
}
.main{
/*main的height值由内容决定*/
/*当内容不足一屏时，下面的设置不会撑开父元素wrap，此时wrap的min-height设置生效，
* 当内容刚好一屏时，下面的设置开始撑开父容器，其height值为100%+50px。
* 拉开这50px的原因是防止footer遮盖住main内容，这个值不是固定死的，由footer的高度值决定
* 为footer向上填充margin-top: -50px;做准备
* */
padding-bottom: 50px;
}
.footer{
height: 50px;
line-height: 50px;
background: deeppink;
text-align: center;
margin-top: -50px;
}
</style>
</head>
