My very own guidedog!

Monday, January 31st, 2005

With all my accessibility studies and teachings at work, I thought it’ll be a good idea to do something for charity, and what better than to sponsor a puppy to become a guide dog?

I filled out the forms and here he is:

Pure mouse independent CSS popups?

Monday, January 31st, 2005

A lot of people cherish the pure CSS popups technique published by Eric Meyer in the long long ago.

The only problem with these is that they are not accessible. While screen readers and browsers without CSS happily display the texts, users without a mouse have no chance to get to the content of the spans embedded in the links.

What we can do though is use Javascript to check if a mouse is available, and make our CSS dependent on a class set to the body if that is the case:


body.mouseenabled a span{

body.mouseenabled a:hover{

body.mouseenabled a:hover span{



if(!document.getElementById || !document.createElement){return;}


this.className+=this.className?' mouseenabled':'mousenabled';


See it in action here.


  • Keyboard accessible


  • The popups are visible until the user moves the mouse.
  • Visitors need Javascript enabled to see the effect.
