Need help on buttons

I am currently trying to make buttons invisible and just put a sprite/text under it.

So far I made the button invisible, but when I click it, a blue outline appears around the button for a split second, how do I remove that?

Wouldn't it be easier to just use the sprite or text as a button?

To remove the blue outline you'd have to adjust the css, I guess..

button:focus {outline:0;} works in normal css..

how do i use the sprite or text as a button? I can't find a tutorial for that D:

mouse on left click on sprite

or

on sprite touched

• add your action..
