I'm completely stumped on this one - I have a pretty basic document with an ordered list containing anchors and hidden divs that show when a link is clicked. The problem is when one link is clicked all links change colour as per the a:visited css rule. This does not happen in IE10 (only the visited link changes colour as expected) but it does happen in Opera, Chrome and Firefox.
Here's the markup: http://jsbin.com/usUwecE/3/edit - I'm pretty new to web design so it could be something really obvious, but any help would be appreciated. Cheers!
