css巧妙实现分隔线

单个标签实现分隔线

.demo_line_01{
    padding: 0 20px 0;
    margin: 20px 0;
    line-height: 1px;
    border-left: 200px solid #ddd;
    border-right: 200px solid #ddd;
    text-align: center;
}

优点：代码简洁

背景色实现分隔线

.demo_line_02{
    height: 1px;
    border-top: 1px solid #ddd;
    text-align: center;
}
.demo_line_02 span{
    position: relative;
    top: -8px;
    background: #fff;
    padding: 0 20px;
}

优点：代码简洁，可自适应宽度

inline-block实现分隔线

.demo_line_03{
    width:600px;
}
.demo_line_03 b{
    background: #ddd;
    margin-top: 4px;
    display: inline-block;
    width: 180px;
    height: 1px;
    _overflow: hidden;
    vertical-align: middle;
}
.demo_line_03 span{
    display: inline-block;
    width: 220px;
    vertical-align: middle;
}

优点：文字可多行

浮动实现分隔线

.demo_line_04{
    width:600px;
}
.demo_line_04{
    overflow: hidden;
    _zoom: 1;
}
.demo_line_04 b{
    background: #ddd;
    margin-top: 8px;
    float: left;
    width: 26%;
    height: 1px;
    _overflow: hidden;
}

利用字符实现分隔线

<div class="demo_line_05">———————————<span>小小分隔线 字符来实现</span>————————————</div>

.demo_line_05{
    letter-spacing: -1px;
    color: #ddd;
}
.demo_line_05 span{
    letter-spacing: 0;
    color: #222;
    margin:0 20px;
}

优点：代码简洁

还有一种利用fieldset标签实现的方法：

html:

<form class="form">
    <fieldset class="fieldset">
        <legend class="legend"><a href="#">可能感兴趣的人</a></legend>
        <div class="btns">
            <a href="#">更多</a><a href="#">111</a>
        </div>
    </fieldset>
</form>

css:

.form{ margin:10px auto; width:800px}
.fieldset{ border-width:1px 0 0; border-color:#ccc; border-style:solid; padding-left:30px;}
.legend{ padding:0 5px;}
.btns{ padding:0 5px; float:right; margin:-18px 10px 0 0; background:#fff; _position:relative }
.btns a{ border-radius:5px; border:1px solid #CCC; padding:3px 7px; margin:0 2px; background:#fff; display:inline-block;}
