I'm having a problem, on smartphone the hover of css3 is not recognized (or rather, it takes about 5 seconds to be recognized), and I wanted to make an interactivity with the photos in my app, as I can not use the hover I'm I do not know what to do, but the solution would be to enlarge the image (or make other effects) when the user clicks / presses it. However I do not know how to do this, I tried a little using Jquery but I could not, I will not post code because I do not have it .. I can put the photo anyway, either as an image or background.
