• 引用符の文字列の回避
• IE bug:color gray bug

specifications (仕様)

• support vendor prefix
• support css hacks. (cssハックは現在未対応です。) ** only underscore hack and asterisk hack.
• セレクタ、プロパティ、値などに含まれるコメントは無視しません。
• 「text-decoration : underline/**/overline;」は適切な内容ですが、 (「text-decoration : underline overline;」と解釈されます。) コメントを無視すると、「underlineoverline」という不明な値になってしまいます。 パーサでは、コメント部分をそのまま返しますが、 バリデータは適切に変換して処理します。

example

css string

@charset "UTF-8";
@import url("style.css") screen , print;
@font-face {
	src: local("Myfont"),url(Myfont.ttf);
}
@page :left {
	margin-left: 4cm;
}
@media screen {
	p {
		font-size: 16px;
	}
}
* #id.class>:link+:lang(ja) ,
div:first-line[attr]:before:after
{
	font-size: 16px;
	xxxxx-xxxx;       /* unknown */
}
