<head><style>.ABC{width:100px; height:100px; background:red; margin:auto; margin-left:20px;}</style></head><body><div class="ABC"></div></body></html>
居中后，似乎不能移位
用绝对定位再margin
不会啊，我刚才用Adobe Dreamweaver 试了一下，
margin-left:20px;margin: 0px auto; //先设置左边距，然后居中，后面的居中会把左边距覆盖掉
margin: 0px auto; margin-left:20px;//先居中，然后设置左边距，后面的左边距会把居中覆盖掉
可能是里面的内容蹭的太大，可能有其他原因，，，，，，
.abc{width:100px;height:100px;background-color:#ccc;position:relative;margin-left:50%;left:-70px;}
