DIV CSS網頁製作小技巧：li中出現兩個以上浮動時 列表標記出現問題的解決辦法。
在LI中定義了兩個以上float浮動，其中有一個左浮動。IE中列表標記跑到右邊，ff中自己定義一行。看下面的代碼：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "//www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="//www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>無標題文檔</title><style>ol {list-style:inside;}span {display:block; float:left; margin:0 6px;}</style></head><body><ol><li><span><a href="#">文字</a></span><span><a href="#">文字</a></span><span><a href="#">文字</a></span></li></ol></body></html>
[Ctrl+A 全部選擇 提示：你可先修改部分代碼，再按運行]
列表的LI在IE中，定了寬後，序號就變為1；定了浮動後，就沒有了序號，FF卻不同。IE認為：列表本來就不把序號算在實體內。在實際應用中，應該避免出現這樣的問題！
