我为我的网站做了一个即时搜索功能，你可以在这里看到:harrisonbh.com/chatterr/instant_search/但搜索结果只是向下推内容。

我不确定我是否应该使用position: absolute;或如何解决这个问题。你觉得我该怎么做?谢谢。
在<div style="float:left;">中包含您的输入文本字段和搜索按钮
我的意思是，像这样:
<div style="float:left;">
<span id="box">
<input type="text" id="search_box"><button id="search_button">Search</button>
</span>
<div id="search_result">
</div>
</div>
