Apply Hover Effect to All Images, Blog Posts

I am trying to apply a hover effect to the images on my blog posts. Upon hovering, I want the images to show an opaque overlay with a button to Pin to Pinterest. I can code it successfully for a fixed image, but can’t seem to figure out how to apply the hover to all images on my blog posts. Thank you in advance!

Hi Megan,

Are you using the Wix Blog application?
At this time, it does not expose the APIs for Wix Code, and Wix Code is not able to effect the content of the blog application. We are on it, we know we should fix this.
