Improving CSS syntax highlighting in vim

Question

CSS syntax highlighting in vim is not entirely optimal. For instance:

div.special_class

stops the selection on _.

Is there an improved marker that does not bite the underscore?

Update: I am using VIM-Vi IMproved 7.1 (2007 May 12, compiled 06/17/2008 15:22:40)

and the title of my css.vim:

" Vim syntax file
" Language:     Cascading Style Sheets
" Maintainer:   Claudio Fleiner <[e-mail]>
" URL:          http://www.fleiner.com/vim/syntax/css.vim

Answer 1

I do not have this problem. This is the header of my syntax file:

" Vim syntax file
" Language: Cascading Style Sheets
" Maintainer:   Claudio Fleiner <[e-mail]>
" URL:      http://www.fleiner.com/vim/syntax/css.vim
" Last Change:  2007 Nov 06

Corresponding syntax file line:

syn match cssClassName "\.[A-Za-z][A-Za-z0-9_-]\+"

Answer 2

What version of vim are you using?

My css.vim

" Vim syntax file
" Language: Cascading Style Sheets
" Maintainer:   Claudio Fleiner <[e-mail]>
" URL:      http://www.fleiner.com/vim/syntax/css.vim
" Last Change:  2005 Nov 23

shipped with vim 7.0 and does not reveal the behavior you described.
