定义一个前端div
<div class="site-search">
<div id="search">
<input type="text" name="s" class="text" placeholder="输入关键字搜索" />
<button type="button" onclick="javascript:doSearch();" class="submit">搜索</button>
</div>
</div>
关键代码,样式调整
.site-search{
    width:25%;
    float:right;
    width:250px;
    height:50px;
}
#search{
    position:relative;
    margin-top:15px;
}
#search input{
    padding-right:30px;
}
#search button{
    position:absolute;
    right:4px;
    top:2px;
    border:none;
    padding:0;
    width:24px;
    height:24px;
    background:url("static/images/search.png") no-repeat scroll right center transparent;
    direction:ltr;
    text-indent:-9999em;
}实现效果
