so I have an image which i would like to overlay with an html button attribute like so:
here is a blank image
i would like to overlay a button like so on the image
and then if the button is clicked have it then look like this
from what i can gather this could be done using CSS using {index-z} somehow, or possible with html5 canvas tag. and then to handle the actually button click with java script.
However i am not completely sure how to accomplish this (the handling of button click with javascript i do know). Could someone link to a tutorial on how to do this or give an explanation it would be greatly appreciated.
Note: the image itself is also an href / link if this changes how this should be done, additionally te image itself will be in a sort of gallery with around 50 similar images or so
