What DOM/CSS/Javascript Stuff Do Not Work In IE5/IE6?

Hi,
I am trying to get my javascript/dom/css code to work with IE5/6. My code works great in Firefox, but not in IE. Do you know of a website that lists all the known javascript/dom/css stuff that don't work in IE?

Many thanks.

I just did further debugging and found that IE6 has problem with style.naturalHeight/naturalWidth, I use alert() to output the naturalHeight in IE and it shows "undefined". I did a search online, and people say that naturalWidth/Height work in IE.

Any other way to find image's original width/height? It's because not all the <img> has width or height defined in the html.

I just tried "if(img.complete)" in img.onload, and found that the loading is not complete even though IE already trigger onload function. Weird! Firefox never has that problem.

Another weird thing:

I put the following inside the img.onload function:

if(!img.complete) {

alert(img.readyState);
}


it says "complete"!!! So img.complete says "not complete", but readyState says "complete"!

What the...
