Themes change the colors and feel of your page. They are built in, no extra cost.
Open the dashboard, click Themes, browse, click one to apply. Live preview before you save.
Custom colors
If a theme is almost right, you can tweak the background, accent, and text colors. Your tweaks save with the theme, so flipping themes resets them.
Light or dark
Each theme picks one. We do not auto switch based on visitor preference because creators usually have a strong opinion about how their page should look.
