Adding additional descriptions on gallery hover

Site URL: https://matthewkoscica.com/

Hi there, 

I'm using the Flatiron template and when I'd love to add a small description to the hover instead of "view".
Currently when you hover you get something like Page Name "-view-" , but would love to replace the "view" with a small bit of text like "lighting" or "concept", unique to each project description.

Is there a good way to do this?

Thanks!

.project-title h3 {
    visibility: hidden;
}
.project-title h3:before {
    visibility: visible;
    content: "Click";
    display: block;
    text-align: center;
}
