jquery: speed difference between .css vs append to head?

Question

We have some kludgy workarounds for an internal app and I was wondering which jQuery/css technique is considered faster / more efficient ...etc.

Technique A

Answer 1

jQuery's .css is faster than appending to head with the sample you provided. I have created a test case which demonstrates this here: http://jsperf.com/jquery-css-vs-append-to-head

As far as offsite CSS, its not comparable, because offsite css speed is dependent on the users internet connection, along with your server speed ect. If you have a wicked server and broadband users, I say offsite is much better, otherwise for speed you can only reliably count on javascript.
