应用这些样式，减少代码量。
<style>
.row {
border:1px solid red;
float:left;
}
.column{
float:left;
margin:10px;
border:1px solid black;
width:24%;
}
.clear{clear:both;}
具有以下HTML结构
<div class="container">
<div class="row">
<div class="column">
<p>loren ipsum</p>
</div>
<div class="column">
<p>loren ipsum</p>
</div>
<div class="column">
