今天看到了这样一道题

用两种不同的方法来实现一个两列布局，其中左侧部分宽度固定、右侧部分宽度随浏览器宽度的变化而自适应变化

自己感觉有好几种方法，再此总结下：

一、使用position：absolute方法，因为把元素设置为absolute，那元素就脱离了文档流，后面的元素就会占据他原来的位置：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><style type="text/css">        .side{width:190px;height:80px;background-color:#F00;<strong>position:absolute;</strong>}    .exta{height:80px;background-color:#0f0;<strong>margin-left:190px;</strong> }        </style><body>    <div class="pd">           <div class="side">side</div>        <div class="exta">exta</div>    </div></body></html>

二、使用float方法

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><style type="text/css">       .side{width:190px;height:80px;background-color:#F00;   　　<strong> float</strong><strong>:left;</strong>    }    .exta{height:80px;background-color:#0f0; }//<strong>不能添加float:left;否则其宽度就会随内容变窄，不是随浏览器变化了</strong>        </style><body>    <div class="pd">                <div class="side">side</div>        <div class="exta">exta</div>    </div></body></html><br /><br />
