javascript - How can I reference the <HTML> element's corresponding DOM object?

This is how you access the <body> element to set a background style:

document.body.style.background = '';

But how can I access the <html> element in a similar manner? The following doesn't work:

document.html.style.background = '';

The <html> element can be referred through the document.documentElement property. In general, the root element of any document can be referred through .documentElement.

document.documentElement.style.background = '';

Note: .style.background returns the value for background as an inline style property. That is, defined using <html style="background:..">. If you want to get the calculated style property, use getComputedStyle:

var style = window.getComputedStyle(document.documentElement);
var bgColor = style.backgroundColor;
