Yes, I also find this the major thing holding me back from HTML presentations. I wrote a HTML presentation for a conference and didn't realise this was a problem until I came to present it, and found out there doesn't seem to be any way to cleanly enlarge / shrink HTML.

EDIT: After a very quick reply to a bug report, I decided to try zoom in/out in Chrome. For anyone else who hasn't tried this in a very long time, the zoom in/out actually does a very good job, allowing me to resize slides to the correct size. Some time after the introduction of CSS2 I found zoom in/out became useless. Turns out at some point it became useful again.

That's good and I'll definitely try Chrome. But, wouldn't it be great if the library/framework just took care of that? In fact, one of the frameworks -- Shining -- referred from the other post has a JavaScript plug-in that seems to do the resizing for different resolutions (although it's implemented in the ugliest way possible, IMO).

I believe both firefox and ie does fine with zoom as well. No need to support edge cases in a library like thia, imho.

Scaling a presentation is not an edge case -- as other commenters have mentioned, working with undesirable screen resolutions is the default for presenters. It would be better to have the presentation scale automatically to the window size than to have to press Ctrl+/Ctrl- to try to get it reasonably close.

My understanding is that, for a while, browser zoom would only scale em values and (of course) percentages. Pixel values stayed fixed regardless of the zoom. Recently, browsers began scaling pixel values as well and most modern browsers can now zoom quite nicely. [citation needed]

as usual, opera was first to implement that, a looong time ago. it also has auto fit width/height options, so i think it deserves a try as well.

Pretty sure IE 5 for the Mac was the first browser to implement that feature back in the day.
