js怎么无效?

Question

想让theDivmd位置靠下1些,怎么不行啊? 哪错了?

Answer 1

<div id="theDivmd" style="padding-top:10px"></div>请问怎么发不了文章？？

Answer 2

top只能在position:absolute或position:relative才有效．好好学学ＣＳＳ

Answer 3

<script language =javascript >
var oDiv = document.getElementById('theDivmd');
oDiv.style.position = 'absolute'
oDiv.style.top =  300 + "px";</script>
