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

- </div>
- <div class="center" style="background-color: pink;">
- <p>center</p>
- </div>
- <div class="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;}

- </style>
-

- <div class="center" style="background-color: pink;">
- <p>center</p>
- </div>
- <div class="right" style="background-color: lightgreen;">

- <p>center</p>
- </div>
- <div class="rightWrap">
- <div class="right" style="background-color: lightgreen;">

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
