標籤：style width re c html 代碼 div ar
範例程式碼如下（相容主流瀏覽器和ie6以上的ie瀏覽器）：
<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"><title></title><style></style></head><body><div id="test"></div></body><script src="../lib/jquery-1.8.3.min.js"></script><script>var style = document.createElement("style");style.type = ‘text/css‘;$("body").append(style);var sheet = style.sheet ? style.sheet : style.styleSheet;if(sheet.insertRule){sheet.insertRule("#test{width:100px;height:100px;background:red;}",0);} else {sheet.addRule("#test", "width:100px;height:100px;background:red;", 0);}</script></html>
以下兩句代碼不能互換順序，否則在大多數瀏覽器上無法擷取sheet（瀏覽器吧style當做一個普通的dom處理，而不是一個樣式表）
$("body").append(style);var sheet = style.sheet ? style.sheet : style.styleSheet;
