- coloured scrollbars (illegal code)
- text filters such as glow text, dropshadow text and alpha opacity (also illegal code)
- image maps
- iframes (!)
There is literally a heap of Internet Explorer-specific code that doesn't work in other commonly-used browsers like Netscape and Firefox. Some code just doesn't show up, but some causes horrible page errors like offset of positioning or makes the page unintelligable.
It's worth checking that what you want to do is legal code, or universally visable, and if not, what the effect will be on people using other browsers. If you want your site to be visable to as many people as possible, you need to cut back on the bad coding practice. It isn't fair just to say "well everyone should use Internet Explorer" because some people can't, or don't want to. You have to accomodate them.
Iframes are a personal pet peeve of mine. Regular frames require little more effort and make the page function more cleanly in most browsers, yet most people use Iframes. Don't do it. I feel as passionately about this as about people who can't spell. They might even work in most browsers, I don't know, I just hate them anyway.
But Mary, you've used coloured scrollbars here!
Indeed I have. I made a design choice, knowing that coloured scrollbars just won't show up in most browsers but won't cause funky errors in most, either. It's just something that only I.E. can see, but, I'd like to emphasise, as divadrummer said to me: whether it can see coloured scrollbars or not is not good criteria for choosing a browser.
I hope somebody who actually needs to read any of this stuff joins.
