此功能默认开启

勾选换行则每条规则后换行，否则全部压为一行（MHTML除外）

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:

.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)}压缩border、outline

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
