Selecting the right kind of theme for your forum is the key to attracting more and more people to your forum. Untidy theme may never attract a good amount of people and your website or forum may experience high bounce rate.

I just need the theme to be editable enough where I can choose the colors.

Other than that, as long as it’s simple to use the forum with the theme, I don’t really have a whole lot of requirements.

Readability and mobile responsiveness should always come before flashy graphics when picking a forum theme. People spend a lot of time reading long threads, so clean typography, sensible line spacing, and offering both a comfortable light mode and dark mode make a huge difference.

Whenever I'm styling web interfaces or working on my Jinjalume UI components, I test how the layout looks on a mid-range phone screen first, because a cramped mobile navigation bar will drive visitors away immediately.
