Gallery Grid hiding Title and Description on hover

Site URL: https://www.mikefiechtner.com/wedding

I'm using the Flatiron template FYI

I have several portfolio galleries.  I have them set up using the grid gallery block......when you click on an image it shows the Title and Description when you hover over the image.  I put SEO stuff in the description and I don't want the image title and description to show up.   I want the text to still be in the code to get SEO help but I just don't want it to pop up on hover.  Is there some code to keep it from showing up on hover?  thanks so much!

Add to Design > Custom CSS

.yui3-lightbox2 .sqs-lightbox-meta {
    opacity: 0 !important;
    display: none !important;
    visibility: hidden !important;
}

thank you so much!
