I want to make it so the images on my homepages enlarge when they're hovered over. I want it to be like this: https://www.w3schools.com/howto/howto_css_zoom_hover.asp
I have seen this on many wiki's before, but I have no idea how to implement the code into my homepage. I'm not sure if I need ot import something in MediaWiki:Wikia.css either.
