title: Setting default onclick behavior for <img> tag in generated html
body: <p>So i have a web app I have been building, and I receive generated html from a server for a post, and place it within the body. My question is: is there a way to set a default onclick behavior for the  tag within that message? I'd rather avoid parsing through the html and setting behavior for each tag. I may just be having a brain fart but felt its best just to ask. The goal behind this is to enable a card switch to full screen the image. I just cant figure out how to set the click behavior. Thanks in advance. </p>
