Delayed timers on page with lots of elements

[Lucy]

I'm just wondering, if you have a page with a lot of divs and text - but they're not actually currently doing anything - should this slow down Javascript intervals/timeouts considerably? The page I'm having problems with does, admittedly, have CSS transitions, and I can see how they would cause delays, but I'm not sure why the page itself should before any transitions occur.

That's a fairly vague question. If you're telling the browser to constantly re-render the page then that's going to cause problems with performance.
