#selector {
property: value;
}
(8空格选项卡)
如何配置Vim使其像这样：
#selector {
property: value;
}
(4空格)
如果要在编辑特定文件类型时设置Vim使用特定设置，则需要使用自动命令：
autocmd Filetype css setlocal tabstop=4
这将使得选项卡显示为4个空格。设置expandtab将导致Vim实际上插入空格(其数量由tabstop控制)，当您按tab;您可能希望使用softtabstop使退格工作正常(即，当应该使用标签时，减少缩进，而不是总是一次删除一个字符)。
要做一个完全教育的决定如何设置，你需要阅读Vim docst on tabstop，shiftwidth，softtabstop和expandtab。最有趣的位在expandtab(：help’expandtab)下找到：
There are four main ways to use tabs in Vim:
Always keep ‘tabstop’ at 8,set ‘softtabstop’ and ‘shiftwidth’ to 4 (or 3 or whatever you prefer) and use ‘noexpandtab’. Then Vim will use a mix of tabs and spaces,but typing and will behave like a tab appears every 4 (or 3) characters.
Set ‘tabstop’ and ‘shiftwidth’ to whatever you prefer and use ‘expandtab’. This way you will always insert spaces. The formatting will never be messed up when ‘tabstop’ is changed.
Set ‘tabstop’ and ‘shiftwidth’ to whatever you prefer and use a |modeline| to set these values when editing the file again. Only works when using Vim to edit the file.
Always set ‘tabstop’ and ‘shiftwidth’ to the same value,and ‘noexpandtab’. This should then work (for initial indents only) for any tabstop setting that people use. It might be nice to have tabs after the first non-blank inserted as spaces if you do this though. Otherwise aligned comments will be wrong when ‘tabstop’ is changed.
