Thread:Talk:Athena/Browser compatibility/reply (2)

Do any of these work reliably across browsers? I'm pretty sure a bunch of old-ish browsers don't support the overflow property, and some browsers have problems with the scroll event and/or touch events, I think. Many browsers do support position:fixed, and for them it would be preferable to use it. Would it be possible to serve position:fixed to some browsers, JS/overflow-based workarounds for those that don't support it, and some entirely different design for the hopeless (or non-javascript supporting) browsers?
