Web Page Complexity Limits - If there are any

i was wondering i am having

• jQuery
• Javascript
• Javascript Timers
• CSS
• DIVs    inside DIVs
• Tables inside Tables
• Table   inside DIVs
• DIVs     inside Tables

and all possible combination of all of the above in one webpage and my website is consisted of su开发者_运维百科ch many pages and worst all these pages are generated with PHP...

i was wondering is there some point where its like OKAY THATS ENOUGH FOR BROWSER, NO MORE complexity...

My Facebook news-feed page (with 'Older posts' clicked a few times) contains nearly 20,000 tags, and still scrolls smoothly. You're going to have a bloated and slow-loading page far before the user's browser gives in.

I think a browser has no complexity limit, except the memory, disk space limit the computer itself has. Are you doing an experiment or actually making a practical site with full of elements?
