两列布局方式：(使用float之后，一定要给div指定宽度。)
1、float IE6 有3px偏移 在left上加 margin-left: -100px
.left{
background-color: red;
float: left;
100px
}
.right{
background-color: green;
margin-left: 110px
}
<div class="content">
<div class="left">left</div>
<div class="right">
<p class="e">qqq</p>
<p>2w</p>
</div>
</div>
2、float+margin+fix用float：left 和right
<div class="content">
<div class="left">left</div>
<div class="right-flx">
<div class="right">
<p class="e">qqq</p>
<p>2w</p>
</div>
</div>
</div>
.left{
background-color: red;
float: left;
100px;
position: relative;
}
.right{
background-color: green;
margin-left: 100px
}
.right-fix{
background-color: blue;
float: right;
100%;
margin-left: 100px
}
3、overflow
.left{
background-color: red;
float: left;
100px;

.right{
background-color: green;
overflow: hidden;
}
<div class="content">
<div class="left">left</div>
<div class="right">
<p class="e">qqq</p>
