第一种:左侧用margin-right,右侧float:right

CSS代码:

html,        body,ul,li        #wrapper {            width: 100%;            height: 100%;            padding: 0;            margin: 0;        }                .left,        .right {            min-height: 500px;            border: 0;        }                .left {            background-color: #999999;            margin-right: 151px;                    }                /*左适应右固定第一种*/        .right {            background-color: #808080;            width: 150px;            float: right;        }                .content {            background-color: #CCCCCC;            /*padding-right: 150px;*/            /*width: 100%;*/        }                .content li{            float: left;            width: 150px;        }

html代码:

<div id="wrapper">            <div class="right">                右侧菜单            </div>            <div class="left">                <div class="content">                    <ul>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                        <li>我是sad放假阿萨洛夫 </li>                    </ul>                </div>            </div>        </div>

第二种:左侧同样用margin-right 右侧采用绝对定位

CSS代码(只需要把第一种注释部分替换即可):

/*左适应右固定第一种*/        /*.right {            background-color: #808080;            width: 150px;            float: right;        }*/                /*左适应右固定第二种(把上面的替换为改代码即可)*/        .right {            background-color: #808080;            width: 150px;            position: absolute;            top: 0px;            right: 0px;        }
Copy after login

第三种:左右浮动都浮动 且 右侧用负margin值

CSS代码:

.wrap {                overflow: hidden;                background: #EEE;            }                        .wrap-right {                width: 300px;                /*position: relative;*/                float: right;                margin-left: -300px;                background: #AAA;            }                        .wrap-left {                width: 100%;                float: left;            }                        .left-con {                margin-right: 300px;                background: #DDD;            }                        .left-con,            .wrap-right {                height: 300px;            }
Copy after login

HTML代码:

<div class="wrap">            <div class="wrap-left">                <div class="left-con">                    我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc我是cccccccccccc                </div>            </div>            <div class="wrap-right">                <a href="" target="_blank">我是mmmmmm</a>            </div>        </div>
