Hello! I am working in my new web page with the miller-template. I want to share all my product design projects in a gallery collection page named work (https://support.squarespace.com/hc/en-us/articles/208216828-Collection-pages). I want to add a hover effect on these images but the template does not give this option. The codes I found on the internet are not working. Could anyone help me with the custom code?
