为什么居中了之后不能再向左挪20px?
为什么顺序改了就提示代码错误啊?
.ABC{width:100px; height:100px; background:red; margin-left:20px; margin:auto;}
一定要使用相对定位或者绝对定位才能实现div居中后再往左或往右挪吗?


回复讨论(解决方案)

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;}
