> As you see there is a tile with circles. This circles are clickable, but the li’s around them are also clickable..why? I just want the circles to be clickable
Because you are not using border-radius but circle images. Basically, this is your image (graphic layer) which is rounded instead of your element.
Try a normal image with border-radius: 50%. It should give you what you’re looking for.
Edit: however Chrome has some problem with this. You can’t do much about it. But it will work for other browsers.
