Hardly. What counts for a search engine is textual content, it will filter out everything else.

I assume CSS comes into play with search engines when they determine whether a portion of text is visible on the page, or hidden for the purposes of SEO. But even there, whether the CSS inline or in a style sheet won't make a difference.

One could argue that the more CSS and JS a page contains, the less weight do search terms have on that page. But I think that argument is invalid, because any non-content content will simply be ignored altogether.
