Display Title & Description On Hover for Gallery Grid

I've been trying to display the title and description of these images in a gallery grid on hover. I've been searching the forums and found some helpful code, but nothing that's exactly what I'm looking for. 

This is the code I am currently using (see below). It is displaying only the title on hover. I need it to display the title and description on hover. Does anyone have any suggestions?

I'd also love the opacity to cover the entire image (right now it covers almost all but just the sliver of the top isn't covered). Let me know if anyone has any suggestions. Thank you!

.sqs-gallery-block-grid .slide .margin-wrapper .image-slide-title {
 display: block; 
 position: absolute;
 top: 0;
 right: 0;
 bottom: 0;
 left: 0;
 padding-top: 5em;
 -webkit-transition: all 300ms ease-out; 
 -moz-transition: all 300ms ease-out; 
 -o-transition: all 300ms ease-out; 
 -ms-transition: all 300ms ease-out; 
 transition: all 300ms ease-out; }

.sqs-gallery-block-grid .slide .margin-wrapper:hover .image-slide-title {
 background: rgba(240,240,240,0.8); }

.sqs-gallery-block-grid .slide .margin-wrapper .image-slide-title {
 font-family: sans-serif, futura pt ;
 font-size: 14px;
 font-style: bold;
 text-transform: uppercase;
 letter-spacing:4px;
 color: #fff;
 opacity: 0; }

.sqs-gallery-block-grid .slide .margin-wrapper:hover .image-slide-title {
 font-family: sans-serif, futura pt;
 font-size: 14px;
 font-style: bold;
 text-transform: uppercase;
 letter-spacing:4px;
 color: #000;
 opacity: 1; }
