Styling applied only once afer page reception?

[R-W-C]

Hello,

I have got the impression the styling is applied only once after page reception. Is that correct? Or did I miss something?

If yes, wouldn't it be useful (and in my opinion) logical to have a button available to reapply the styling?
A lot of times the page is changed because some javascript is being executed (AJAX calls). Think of adding or modifying divs on the page or loading new content for iframes. And maybe it could be a good idea to have the styling reapplied with a configurable interval. Thoughts?
