我做了一些挖掘，并建议一个替代解决方案。

I did some more digging and would like to suggest an alternate solution.

1. 在Sublime中打开〜/ Library / Application Support / Sublime Text 2 / Packages / CSS / css_completions.py 。

在第190行，删除冒号后面的空格：

On line 190, remove the space after the colon:

l.append((p, p + ": "))

我可以想到的唯一注意事项是的，这可能会覆盖，当你更新Sublime，但这似乎很好没有安装额外的包。

The only caveat I can think of is that this might get overwritten when you update Sublime, but this seemed to work great without installing an extra package.
