圣杯布局、双飞翼布局效果图
从效果图来看圣杯布局、双飞翼布局效果是一样一样的。
圣杯布局、双飞翼布局就是左右两侧宽度固定，中间内容宽度自适应，即100%
圣杯布局
<style>
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.clearfix:before,
.clearfix:after{
display: table;
content: " ";
clear: both;
}
.container{
padding: 0 200px;
}
.header,
.footer{
height: 200px;
font-size: 28px;
background-color: #f3f3f3;
}
.left{
position: relative;
/* 2、将.left再次拉到最左边，否则.main的左侧会有200px的空白 */
left: -200px;
float: left;
width: 200px;
min-height: 300px;
/* 1、将.left拉到最左边，原来.left是掉下去的 */
margin-left: -100%;
background-color: #f00;
}
.main{
float: left;
width: 100%;
min-height: 300px;
background-color: #c32228;
}
.right{
position: relative;
/* 2、将.right再次拉到最右边，否则.main的右侧会有200px的空白 */
right: -200px;
float: left;
width: 200px;
/*/1、将.right拉到最右边，原来.right是掉下去的 */
margin-left: -200px;
min-height: 300px;
background-color: #f90;
}
</style>
<div class="header">header</div>
<div class="container clearfix">
<div class="main">main</div>
<div class="left">left</div>
<div class="right">right</div>
</div>
<div class="footer">footer</div>
浮动实现双飞翼布局
<style>
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.clearfix:before,
.clearfix:after{
display: table;
content: " ";
clear: both;
}
.header,
.footer{
height: 200px;
font-size: 28px;
background-color: #f3f3f3;
}
.left{
float: left;
width: 200px;
min-height: 300px;
/* 将.left拉到最左边，原来.left是掉下去的 */
margin-left: -100%;
background-color: #f00;
}
.main{
float: left;
width: 100%;
min-height: 300px;
/* .left、.right各占了200px，因此需要将其抵消掉 */
padding: 0 200px;
background-color: #c32228;
}
.right{
float: left;
width: 200px;
/* 将.right拉到最右边，原来.right是掉下去的 */
margin-left: -200px;
min-height: 300px;
background-color: #f90;
}
</style>
<div class="header">header</div>
<div class="container clearfix">
<div class="main">
<div class="main-inner">main</div>
</div>
<div class="left">left</div>
<div class="right">right</div>
</div>
<div class="footer">footer</div>
table-cell实现双飞翼布局(IE8也兼容哦~)
<style>
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.container{
display: table;
}
.header,
.footer{
height: 200px;
font-size: 28px;
background-color: #f3f3f3;
}
.left,
.right,
.main{
/* 外层容器使用table-cell布局，设置元素为table-cell布局后它们就能在一行显示了，display: table-cell;设置宽度无效，
因此他们的宽度由内容撑开。 */
display: table-cell;
}
.left-inner{
width: 200px;
min-height: 300px;
background-color: #f00;
}
.main{
width: 100%;
}
.main-inner{
min-height: 300px;
background-color: #c32228;
}
.right-inner{
width: 200px;
min-height: 300px;
background-color: #f90;
}
</style>
<div class="header">header</div>
<div class="container clearfix">
<div class="left">
<div class="left-inner">left</div>
</div>
<div class="main">
<div class="main-inner">main</div>
</div>
<div class="right">
<div class="right-inner">right</div>
</div>
</div>
<div class="footer">footer</div>
绝对定位实现双飞翼布局
使用绝对定位实现有个小问题：父容器的高度只能由.main的高度来决定
<style>
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.container{
position: relative;
padding: 0 200px;
}
.header,
.footer{
height: 200px;
font-size: 28px;
background-color: #f3f3f3;
}
.left{
position: absolute;
top: 0;
left: 0;
width: 200px;
min-height: 300px;
background-color: #f00;
}
.main{
min-height: 300px;
background-color: #c32228;
}
.right{
position: absolute;
top: 0;
right: 0;
width: 200px;
min-height: 300px;
background-color: #f90;
}
</style>
<div class="header">header</div>
<div class="container clearfix">
<div class="left">left</div>
<div class="main">mian</div>
<div class="right">right</div>
</div>
<div class="footer">footer</div>
使用flex实现双飞翼布局(有兼容性问题)
<style>
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
.clearfix:before,
.clearfix:after{
display: table;
content: " ";
clear: both;
}
.container{
display: flex;
}
.header,
.footer{
height: 200px;
font-size: 28px;
background-color: #f3f3f3;
}
.left{
flex: 0 0 200px;
width: 200px;
min-height: 300px;
background-color: #f00;
}
.main{
flex: 1;
width: 100%;
min-height: 300px;
background-color: #c32228;
}
.right{
flex: 0 0 200px;
width: 200px;
min-height: 300px;
background-color: #f90;
}
</style>
<div class="header">header</div>
<div class="container clearfix">
<div class="left">left</div>
<div class="main">main</div>
<div class="right">right</div>
</div>
<div class="footer">footer</div>
