and am trying to deficer it, thanks.

* html #someID form {
margin: 0 0 0 0;
padding: 0 0 0 0;
}

* matches "any element", so it means "descends from any element"

* html is a common hack to present some CSS to only Internet Explorer.

Since <html> is the root element, it can't descend from anything, but IE
doesn't realise this.

For some reason, IE is under the impression that the HTML element is not
the document root, and there is some element above it. As other browsers
don't suffer the same misconception, this rule would only be applied by IE.
margin: 0 0 0 0;
padding: 0 0 0 0;

These could be shortened to have a singular zero (0) value (in case you
weren't aware).

I have since found it in the W3C documentation. I probably wouldnt have
found it without your help. thanks!

5.3 Universal selector
The universal selector, written "*", matches the name of any element
type. It
matches any single element in the document tree. [p. 35]
If the universal selector is not the only component of a simple
selector [p. 67] , the
"*" may be omitted. For example:
*[lang=fr] and [lang=fr] are equivalent.
*.warning and .warning are equivalent.
*#myid and #myid are equivalent.
