Help Html Button Icon

[ElBato]

Greetings all, could give me a little help with this problem that I have with the buttons? This I want to do a few buttons on the html for my NPCs with some icons of skills and items, the problem is when I pass the mouse over this button becomes a black box, the same happens when you make a click.

For example I want to get a result like this:

 

Press:

 

Mouse over the icon:

 

My code: 

<button action="null" back="icon.skill5243_Over" fore="icon.skill5243" width="32" height="32"/>

 

On the back tag, try using "_Over" or "_Down" and nothing happened. Please help..

 

Sorry my english.
