@scorza420 Thank you. That’s true, the UIs are most easily customizable with CSS.
Additionally, some basic styling can be done via the Customizer menu.
@ncury1 It depends on what you’re trying to do. The easiest thing to do is use Customizer or apply some simple CSS. It is also possible, but harder, to modify the markup. For a complete list of things you can do, please consult the FAQ under “I don’t like the built-in forms. Can I change them or provide my own?”
Please let me know if you have any questions about this.
