I've been busy creating a register overlay (which I'll use as a template for all my other overlays), but I was having some issues in Safari with the interactions that I added not functioning properly - they seem to be working now.
The link to my live project is http://ptest1.webflow.com/step-1-begin-campaign (it's very much a work in progress still), but I'd love it if you could click the blue '+ Register' button to check that the Registration overlay pops up, and then hit the 'X' in the overlay to close it again.
If it doesn't work, please let me know which browser you're on. If it works across the board (or most of it, anyway), i'd be happy to show others how I created the overlay.
Also, for those of you that are pros with Webflow, is there a way I can have the slider 'Next' button move relative to the slider? If you click the blue 'Next' button, the button stays in the exact location.
