Thank you so much! For the caption and titles I modified it just a tad so that I could also adjust the line height:
.mfp-figure .mfp-title { font-size: 30px; }
.mfp-figure .mfp-title { line-height: 1em }
.mfp-figure .mfp-title small { font-size: 20px; }
.mfp-figure .mfp-title small { line-height: 1em; }
On the Scrolling, I messed around a bit but wasn’t happy with the results. It is not such a huge deal with the text size issue resolved, will have to come back to it at a later time. I would like put these features in in as a production suggestion, because the inability to show captions in a grid gallery at all is one of the really annoying limitations of Divi. You have already saved me on the masonry feature and being able to show captions.
