Hello there,

I would have to agree with symmet, you need both. This way if a user doesn't have a recent version of Firefox, Google Chrome, Safari or Opera you can have jQuery to fall back on.

-You can use browser detection to conditionally enable jQuery scripts on page load. You can use Javascript/jQuery or a server-side script to detect exactly which browser is loading the page.

-You can also check out http://www.modernizr.com/. It adds classes to the html element which allow you to target specific browser functionality in your stylesheet.

Let me know if you need any help with that,

Good luck!

Karl
