Hey folks, I think that @othree has made a better work here:

Thanks!

good job

great work and thanks for the link of html5.vim

So, sometime, especially if I'm working with D3, my HTML5 documents have CSS, JavaScript, and SVG all embedded in the HTML code. Is there a simple way for syntax highlight all of this?

You can switch the filetype while you're in the CSS portion or whatever -- :set filetype=css or set filetype=javascript etc. I set up a mapping to make it easier, e.g. nnoremap <leader>ftc :set filetype=css<cr>.
