Hello Heidi-
Thanks for reaching out! The way you’ve described it, you should be able to customize your Social Media menu with the steps you’re taking.
I checked out your site, and I do see that the hover effect is currently using fade, but the link colors are still white. I tried replicating the steps you’re taking and it is working for me.
Occasionally, you may need to force the styles to re-compute by changing one style, publishing, changing it back, and publishing once more. If this still isn’t working for you, I’d recommend reaching out to our Premium Support Team so we can take a closer look for you. As a DreamHost customer, premium support is included with your hosting subscription.
