[jQuery] Accessibility, CSS

[jQuery] Accessibility, CSS


Have just joined and nervously used Jquery for the first time. Just
woudering about two thngs:
1. When jquery modifies styles it seems to do in-line styles. I tend
to keep all my styles external. Does it have to do it in-line?
2. I see no mention of accessibility or advice on validating or
accessible javascript discussion. Why not?
Thanks.
