How do I get access to the <html> element in Javascript?
Question
IE displays a default scrollbar on the page, which appears even if the content is too short to require a scrollbar.
The typical way to remove this scrollbar (if not needed), is to add this to your CSS:
html {
height: 100%;
overflow: auto;
}
I'm trying to do the same thing in Javascript (without requiring that in my CSS), but I can't seem to find a way to get access to the <html> element. I know I can access the <body> element with document.body , but that doesn't seem to be sufficient, I need the wrapping <html> element.
Any tips?

I guess for completeness' sake, I'll add another way to access it:
document.getElementsByTagName('html')[0];
Obviously this is a little more verbose, but it's always going to work regardless of the structure or standards-mode of your document.

You can also reach the HTML element with:
var html = document.body.parentNode;
alert(html.nodeName);
