Trackpad Horizontal Scroll & Layered Page Loading

Hi All!
Building my first site with Webflow; enjoying the adventure so far. Help needed on 2 things:

  1. I created a horizontal scrolling gallery of photos but currently users can only cycle through the images by using the arrows at the top left. I’d like to allow both trackpad navigation (2-finger horizontal swiping), and clicking the far right image to move to the next image.

  2. I’d like the project’s “DESCRIPTION” section to load on top of the images with slight transparency. I’m looking for guidance on the best way to achieve that please. Please see the mockups and links below for full context. EDIT: I was able to achieve this by following this excellent tutorial: Build A Basic Popup Modal In Webflow

Any assistance would be deeply appreciated.
