Is there anyway to stop that happening?

 

Thanks

Short answer: no.

 

Long answer: If you're using Javascript to add classes on DOMReady, or doing heavy DOM manipulation, this will delay the final rendering of your page, although it will try to figure it out as each new node is drawn. Be aware that dynamic script inclusion is even slower. I'd say take a good look at your Javascript, that's probably where the problem lies.

 

If you're not using Javascript, take a good look to see if you've got multiple @import rules. Replacing all of those with <link> elements in your markup will speed up your page rendering
