For starters, know where the specifications are. You can use most of CSS 2
with pretty decent conformance all-around:
http://www.w3.org/TR/CSS21/

With regard to cursor, look here:
http://www.w3.org/TR/CSS21/ui.html#propdef-cursor

Compare those with these:
http://msdn.microsoft.com/workshop/author/css/reference/attributes.asp
http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/cursor.asp

Now, cursor:hand presents more of a problem than most things, because the MS
documentation generally does not explain the *little* ways in which IE
departs from standards.

It is better when IE departs in a big way. Take a look here:
http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/clientheight.asp

This comes with a disclaimer:

Standards Information
There is no public standard that applies to this method.

Generally speaking, if the console does not tell you the specific line and
column, you have a parsing error, such as failing to close an open brace.
Otherwise, I find the console messages pretty straigtforward.

Consider your website. When I visit it, I get one JS error:

Error:
document.getElementById(id).contentWindow.document.getElementById(tname) has
no properties
Source File: http://tandcl.homemail.com.au/scripts/external.js
Line: 266

The line in question reads:

var newheight =
document.getElementById(id).contentWindow.document.getElementById(tname).clientHeight

Because of operator precedence**, I know that JS understands everything up
to here:

document.getElementById(id).contentWindow.document.getElementById(tname)_

In other words, document.getElementById(id) returned an object with a
property called "contentWindow", which referred to an object with property
"document", which had a method named "getElementById". If any of those had
failed, your message would have reflected that fact. Since it did not, I
know that getElementById(tname) was called, but the thing returned did not
have a property called "clientHeight", probably because it returned null or
because the uniqueness constraint on ID was violated:

getElementById introduced in DOM Level 2
Returns the Element whose ID is given by elementId. If no such
element exists,
returns null. Behavior is not defined if more than one element has
this ID.

I use these MS references:

In addition, I use these W3C references:
HTML 4.01: http://www.w3.org/TR/html4
XHTML 1.1: http://www.w3.org/TR/xhtml11
DOM (mostly 1 and 2): http://www.w3.org/DOM/DOMTR
