I am working on upgrading some of my addons to work with 5.7. I have gotten a few of them to install just fine. Now, I just need to make the front-end editor form interface look pretty.

Tabbed Interface - Currently, the tabs appear as an unordered list with no styling. They work just fine, but the tabs don't show up. How do I fix this?

Color Picker - The color picker doesn't show up at all, and only displays a text field. What's the proper way to add a color picker for 5.7?
