三栏布局（7种方式实现）

1、浮动布局

<div class="container">
    <div class="left col">left</div>
    <div class="right col">right</div>
    <div class="main col">main</div>
</div>

.col {
    min-height: 100px;
    background: #eee;
    border: 1px solid #666;
}
.left {
    float: left;
    width: 100px;
}
.right {
    float: right;
    width: 100px;
}
.main {
    margin: 0 102px;
}

2、绝对定位

<div class="container">
    <div class="left col">Left</div>
    <div class="right col">Right</div>
    <div class="main col">Main</div>
</div>

.container {
    position: relative;
}
.col {
    min-height: 100px;
    background: #eee;
    border: 1px solid #666;
}
.left, .right {
    position: absolute;
    top: 0;
}
.left {
    left: 0;
    width: 100px;
}
