Adjusted vertical layout's description paragraph height to fix the bug where the 'Read more' button was overlapping the first thumbnail. This adjustment was made with design input from Earl. I also switched the CSS file to SASS and nested the selectors properly. Despite the large refactor, the only change is in the height mentioned above.
