Thank you for your reply. Following your instructions, I added a static block with the icons, then added the static block widget to the top bar widget area.
2 things:
1. Only 2 of the 4 icons show on the homepage, but all 4 show on every other page. Not a deal breaker, but if there is an easy fix I’d like to know.
2. What code would I add t custom CSS (and corresponding class to the static block) to add a hover effect to the icons?
Thank you so much for your support!
