一、两侧定宽中间自适应布局
思路一: float
【1】float + margin + calc
- <style>
- p{margin:0;}
- .parent{overflow:hidden;}
- .left,.rightright{float:left;width:100px;}
- .center{float:left;width:calc(100%-240px);margin:020px;}

- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="centerWrap"style="background-color:red;">
- <divclass="center"style="background-color:pink;">
- <p>center</p>
- <p>center</p>
- </div>
- </div>
- <divclass="right"style="background-color:lightgreen;">
- <p>right</p>
- </div>
- </div>
思路二: inline-block

- .parent{font-size:0;}
- .left,.rightright,.centerWrap{display:inline-block;vertical-align:top;font-size:16px;}
- .left,.rightright{width:100px;position:relative;}
- .centerWrap{width:100%;margin:0-100px;}
- .center{margin:0120px;}
- </style>
- <divclass="parent"style="background-color:lightgrey;">

二、两列定宽一侧自适应布局
这种布局与单列定宽单列自适应布局非常相似
思路一: float
【1】float + margin
缺点是IE6-浏览器的3px的bug,以及当自适应列中有元素清除浮动时,会使该元素不与左侧浮动元素同行,从而出现文字下沉现象
- <style>
- p{margin:0;}
- .parent{overflow:hidden;}
- .left,.center{float:left;width:100px;margin-right:20px;}
- .rightright{margin-left:240px;}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">
- <p>center</p>
- </div>
- <divclass="right"style="background-color:lightgreen;">
- <p>right</p>
- <p>right</p>
- </div>
- </div>
【2】float + margin + calc
- <style>
- p{margin:0;}
- .parent{overflow:hidden;}
- .left,.center{float:left;width:100px;margin-right:20px;}
- .rightright{float:left;width:calc(100%-240px);}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">
- <p>center</p>
- </div>
- <divclass="right"style="background-color:lightgreen;">
- <p>right</p>
- <p>right</p>
- </div>
- </div>
【3】float + margin + (fix)
- <style>
- p{margin:0;}
- .parent{overflow:hidden;}
- .left,.center{position:relative;float:left;width:100px;margin-right:20px;}
- .rightWrap{float:left;width:100%;margin-left:-240px;}
- .rightright{margin-left:240px;}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">
- <p>center</p>
- </div>
- <divclass="rightWrap">
- <divclass="right"style="background-color:lightgreen;">
- <p>right</p>
- <p>right</p>
- </div>
- </div>
- </div>
【4】float + overflow
- <style>
- p{margin:0;}
- .parent{overflow:hidden;}
- .left,.center{position:relative;float:left;width:100px;margin-right:20px;}
- .rightright{overflow:hidden;zoom:1;}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">
- <p>center</p>
- </div>
- <divclass="right"style="background-color:lightgreen;">
- <p>right</p>
- <p>right</p>
- </div>
- </div>
思路二: inline-block
【1】inline-block + margin + calc
- <style>
- p{margin:0;}
- .parent{font-size:0;}
- .left,.rightright,.center{display:inline-block;vertical-align:top;font-size:16px;}
- .left,.center{width:100px;margin-right:20px;}
- .rightright{width:calc(100%-240px);}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">

- .rightWrap{width:100%;margin-left:-240px;}
- .right{margin-left:240px;}
- </style>
- <divclass="parent"style="background-color:lightgrey;">
- <divclass="left"style="background-color:lightblue;">
- <p>left</p>
- </div>
- <divclass="center"style="background-color:pink;">

总结
三列布局类似于大号的两列布局。无论是什么布局方式,无外乎需要应用float、inline-block、table、absolute和flex这五种布局属性,然后再配合负margin、calc()函数、bfc、增加结构等来实现布局
自适应包括两种情况:一种是宽度由内容撑开,一种是宽度自动撑满父元素剩余宽度
可实现宽度由内容撑开的属性有: float、inline、inline-block、table、table-cell、absolute、fixed和flex
可实现宽度自动撑满父元素剩余宽度的属性有: overflow(配合float)、table、flex
到此这篇关于CSS三列布局的多种表现形式就介绍到这了。青春,一个被赋予太多憧憬与希望的词汇。在很多人眼里青春如火,燃烧着激情与活力;青春如花,绽放着智慧和希望。但在我的眼里,青春就如一只迷途的鹿,徘徊在人生的十字路口,前路是满布的荆棘与彷徨。更多相关CSS三列布局的多种表现形式内容请查看相关栏目,小编编辑不易,再次感谢大家的支持!
