Well, I'm now starting programming in HTML5 + JavaScript + CSS and I have a question that I suppose is basic but I can not find an answer. I created an HTML5 canvas and since I was not able to add buttons (created in HTML) on the canvas, I decided to make my own JavaScript buttons. My question is: I wanted to customize the button and as I created it in JS, is there any way for CSS to fetch the button from JS instead of HTML?
