CssGaga参考了一部分YUI Compressor，拥有比YUI Compressor更极限的压缩

去除注释和空白

Before:

/***** Multi-line comment before a new class name *****/
.classname { /* comment in declaration block */ font-weight: normal; }

After:

.classname{font-weight:normal}

去除结尾的分号

Before:

.classname { border-top: 1px; border-bottom: 2px; }

After:

.classname{border-top:1px;border-bottom:2px}

Before:

去除多余的分号

.classname { border-top: 1px; ; border-bottom: 2px;;; }

After:

.classname{border-top:1px;border-bottom:2px}

去除无效的规则

Before:

.empty { ;} .nonempty {border: 0;}

After:

.nonempty{border:0}

去除零值的单位并合并多余的零

Before:

a { margin: 0px 0pt 0em 0%; background-position: 0 0ex; padding: 0in 0cm 0mm 0pc }

After:

a{margin:0;background-position:0 0;padding:0}

去除小数点前多余的0

Before:

.classname { margin: 0.6px 0.333pt 1.2em 8.8cm; background: rgba(0, 0, 0, 0.5); }

After:

.classname{margin:.6px .333pt 1.2em 8.8cm;background:rgba(0,0,0,.5)}

色值压缩

Before:

.color-me { color: rgb(123, 123, 123); border-color: #ffeedd; background: none repeat scroll 0 0 rgb(255, 0,0); }

After:

.color-me{color:#7b7b7b;border-color:#fed;background:none repeat scroll 0 0 #f00}
不压缩RGBA与IE滤镜中的色值

Before:

.cantouch { color: rgba(1, 2, 3, 4); filter: chroma(color="#FFFFFF"); }

After:

.cantouch{color:rgba(1,2,3,4);filter:chroma(color="#FFFFFF")}

去除编码声明

Before:

@charset "utf-8"; 
#foo { border-width: 1px; }
/* second css, merged */ 
@charset "another one"; 
#bar { border-width: 10px; }

After:

#foo{border-width:1px}
#bar{border-width:10px}

压缩IE滤镜

Before:

.classname { -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)"; /* IE 8 */
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=80); /* IE < 8 */ }

After:

.classname{-ms-filter:"alpha(opacity=80)";filter:alpha(opacity=80)}

去除多余引号

Before:

@import url("mod-1.css"); 
@import url('mod-2.css');

After:

@import url(mod-1.css);
@import url(mod-2.css);

Before:

.classname{ background: url("img/icon.png"); }
.classname{ background: url('img/icon.png'); }

After:

.classname{background:url(img/icon.png)} .classname{background:url(img/icon.png)}

不影响正常的引号

Before:

.clearfix:after{content:".";display:block;height:0;clear:both;visibility:hidden;}

After:

.clearfix:after{content:".";display:block;height:0;clear:both;visibility:hidden}

对HACK的影响

支持常用HACK

Before:

#element { width: 1px; width: 2px9; *width: 3px; #width: 3px; _width: 4px; }

After:

#element{width:1px;width:2px9;*width:3px;#width:3px;_width:4px}

不支持以下HACK

html >**/**/** body p { color: blue; }

#elem {
    width: 100px; /* IE */
    voice-family: ""}"";
    voice-family:inherit;
    width: 200px; /* others */
}
