How to create a <style> tag with Javascript?

Question

I'm looking for a way to insert a <style> tag into an HTML page with JavaScript.

The best way I found so far:

var divNode = document.createElement("div");
divNode.innerHTML = "<br><style>h1 { background: red; }</style>";
document.body.appendChild(divNode);

This works in Firefox, Opera and Internet Explorer but not in Google Chrome. Also it's a bit ugly with the <br> in front for IE.

Does anyone know of a way to create a <style> tag that

1. Is nicer

2. Works with Chrome?

Or maybe

1. This is a non-standard thing I should avoid

2. Three working browsers are great and who uses Chrome anyway?

Answer 1

Try adding the style element to the head rather than the body.

This was tested in IE (7-9), Firefox, Opera and Chrome:

var css = 'h1 { background: red; }',
    head = document.head || document.getElementsByTagName('head')[0],
    style = document.createElement('style');

head.appendChild(style);

style.type = 'text/css';
if (style.styleSheet){
  // This is required for IE8 and below.
  style.styleSheet.cssText = css;
} else {
  style.appendChild(document.createTextNode(css));
}
