当我为一个页面编辑HTML时，所有网站页面都是左对齐的，这样右边就有一个巨大的空间。当我检查CSS代码时，所有div标签都使用'auto'定位。重要的是，这发生在我甚至没有编辑的html / css中。这是我的CSS：
/* CSS Document - this does formatting for you*/
/* Erice Myer's Reset, which resets the browser's innate styles to a baseline */
html, body { margin: 0; padding: 0; border 0: background: transparent; font-size: 12px;}

我不确定这是否是一个错字。但是，当你摆弄css的时候，你碰巧改变了这条线吗？
html, body { margin: 0; padding: 0; border 0: background: transparent; font-size: 12px;}
因为如果你仔细观察它所说的部分
border 0: background: transparent;
似乎错了它应该是border: 0; background: transparent;
希望这有帮助

外部div设置为30px的边距。也许您在另一个页面上需要这个并且更改它会改变此页面的布局。

变化：
#outer { width: 960px; margin-top:30px; margin-bottom:30px; margin-left:30px; margin-right:30px; background-color:#FFF; }
致：
#outer { width: 960px; margin:30px auto; background-color:#FFF; }
但是，如果您这样做，我怀疑您在其他网页上会遇到问题，请检查您的共享网址。
