jQuery check if browser support position: fixed

Question

How do I check if browser supports position:fixed using jQuery. I assume I have to use $.support I think, but how?

Thank you for your time.

Answer 1

The most reliable way would be to actually feature-test it. Browser sniffing is fragile and unreliable.

I have an example of such test in CFT http://kangax.github.com/cft/#IS_POSITION_FIXED_SUPPORTED. Note that the test should be run after document.body is loaded.
