武林網(www.survivalescaperooms.com)文章簡介：CssGaga – AutoSprite(CSS Sprite Generator).

市面上有一些sprite生成器，要么是要人工調整圖片位置，要么要拷貝粘貼代碼，用起來總是覺得不夠爽，CssGaga使用了不同的思路，希望能解放你的雙手:) 使用時選中AutoSprite即可開啟此功能，下面通過一個例子來說明：比如HTML：

css源文件：

body{background-color:black;}s{display:inline-block;width:16px;height:16px;overflow:hidden;background-repeat:no-repeat;}.i1{background-image:url('slice/1.png');}.i2{background-image:url('slice/2.png');}.i3{background-image:url('slice/3.png');}.i4{width:64px;height:64px;background-image:url('slice/4.png');}.i5{background-image:url('slice/3.png');}.i6{width:64px;height:64px;background-image:url('slice/6.gif');}.i11{width:60px;height:60px;background-image:url('slice/1.jpg');}.i12{width:60px;height:60px;background-image:url('slice/2.jpg');}.i13{width:60px;height:60px;background-image:url('slice/3.jpg');}.i14{width:60px;height:60px;background-image:url('slice/4.jpg');}

CssGaga生成后：

body{background-color:black}s{display:inline-block;width:16px;height:16px;overflow:hidden;background-repeat:no-repeat}.i1{background-image:url(sprite/style.png);background-position:-128px 0}.i2{background-image:url(sprite/style.png);background-position:-128px -16px}.i3{background-image:url(sprite/style.png);background-position:-128px -32px}.i4{width:64px;height:64px;background-image:url(sprite/style.png);background-position:0 0}.i5{background-image:url(sprite/style.png);background-position:-128px -32px}.i6{width:64px;height:64px;background-image:url(sprite/style.png);background-position:-64px 0}.i11{width:60px;height:60px;background-image:url(sprite/style.jpg);background-position:0 0}.i12{width:60px;height:60px;background-image:url(sprite/style.jpg);background-position:-60px 0}.i13{width:60px;height:60px;background-image:url(sprite/style.jpg);background-position:-120px 0}.i14{width:60px;height:60px;background-image:url(sprite/style.jpg);background-position:-180px 0}

同時生成sprite圖片sprite/style.png和sprite/style.jpg

文件對比：

beforeafter

htmlbefore.htmafter.htm

cssstyle.source.cssstyle.css

imagepng/gif總大小：10.2KB
jpg總大小：8.69KB
slice/1.png
5.83KB
sprite/style.png

詳解

碎圖片放在slice文件夾，slice文件夾與css同級且引用時為相對路徑

css調用圖片的語句不能縮寫，要寫完整background-image:url('slice/1.png')

引號寫單雙無所謂，不寫也行，最后都會被壓縮掉，下面這種寫法不會生效

background:url('slice/1.png')
