Append some HTML into the HEAD tag?

Question

Hi!

I want to add some style to head tag in html page using javascript.

var h = document.getElementsByTagName('head').item(0);
h.innerHTML += '<style>a{font-size:100px;}</style>';

But when I run this code in IE8 I see this error message: Could not set the innerHTML property. Invalid target element for this operation.

Any ideas?

Create the style element with createElement:

var h = document.getElementsByTagName('head').item(0);
var s = document.createElement("style");
s.type = "text/css"; 
s.appendChild(document.createTextNode("a{font-size:100px;}");
h.appendChild(s);
