固定宽度与自适应布局的实现方法:
- 方法一:利用BFC特性
父元素设置
overflow: hidden;
属性
固定宽度元素设置margin-left
left
float
position: relative;
自适应元素设置float
width: 100%;
.bd-lft {
zoom: 1;
overflow: hidden;
padding-left: 210px;
}
.bd-lft .aside {
float: left;
width: 200px;
margin-left: -100%; /*= -100%*/
position: relative;
left: -210px; /* = -pararntNode.paddingLeft */
_left: 0; /*IE6 hack*/
}
.bd-lft .main {
float: left;
width: 100%;
}
- 方法二:position 定位
父元素设置
position: relative
固定宽度元素设置position: absolute;
left: 0;
top: 0
.bd-lft {
zoom: 1;
padding-left: 210px;
position: relative;
}
.bd-lft .aside {
width: 200px;
position: absolute;
left: 0;
top: 0;
}
.bd-lft .main {
width: 100%;
}
