Inline style to act as :hover in CSS

If you are only debugging, you might use javascript to modify the css:

<a onmouseover="this.style.textDecoration='underline';" 
    onmouseout="this.style.textDecoration='none';">bar</a>

I'm afraid it can't be done, the pseudo-class selectors can't be set in-line, you'll have to do it on the page or on a stylesheet.

I should mention that technically you should be able to do it according to the CSS spec, but most browsers don't support it

Edit: I just did a quick test with this:

<a href="test.html" style="{color: blue; background: white} 
            :visited {color: green}
            :hover {background: yellow}
            :visited:hover {color: purple}">Test</a>

And it doesn't work in IE7, IE8 beta 2, Firefox or Chrome. Can anyone else test in any other browsers?
