插件，可以将CSS格式化成一行，也可以将一行格式化成多行。
下载解压缩之后，将compact_expand_css_command.py放到
*Sublime Text 2PackagesUser [windows下一般在安装盘/用户:例:C:UsersxwAppDataRoamingSublime Text 2PackagesUser]
然后，重启一下st2，选择Preferences>Key Bindings - User
加入以下代码：
{ "keys": ["ctrl+shift+]"], "command": "compact_expand_css", "args": { "action": "expand" } },
{ "keys": ["ctrl+shift+["], "command": "compact_expand_css", "args": { "action": "compact" } }
保存，现在再试一下就OK啦！
个人常用对Key的习惯性配制
