Question

what does it mean to have a style sheet disabled?

I just realised that its possible when i visited this page.. https://developer.mozilla.org/en/DOM/HTMLStyleElement

Answer 1

You can disable styles by setting the disabled property on the element that loaded them (either a style element for inline styles, or a link element for linked stylesheets). When disabled, a stylesheet’s rules aren’t applied.

Example:

CSS:

<style id='style2'>
  p {
    color: green;
    font-weight: bold;
  }
</style>

HTML:

<p id ='theParagraph'>Click this paragraph to toggle the <tt>style2</tt> styles.</p>

(I know, I know, tt is deprecated.)

JavaScript:

document.getElementById('theParagraph').onclick = function() {
  var style = document.getElementById('style2');
  style.disabled = !style.disabled;
};
