Doesn't your email client know how to show them in plain text by default? :)

Hi Joseph

First of all, please stop using HTML emails, this is very annoying.

For all the JavaScript hackery we have JavaScript hackery frameworks
like Scriptaculous that do XMLHttpRequest and stuff in a halfway
probable way (way more portable than if you would write it yourself,
this isn't meant offensive, that's just how it is).

You use JavaScript to make CSS designs? This sounds a bit strange.

In 2.7 we have the new header api that should make stuff like this
easier but diffrent CSS according screen resolution doesn't sound
good.
