If there are more in-depth changes you want to make to your design that aren’t included in our built-in theme editor, you’ll need to dig into your code or hire a designer/developer.
For savvy code conquerers
Most theme HTML is editable within all built-in pages, except for checkout. Big Cartel themes also use Liquid markup as the theme’s language. Check out our tech documentation for the full rundown.
When editing your CSS, it’s best to override existing styles at the bottom of Design > Code > CSS instead of editing the code directly, especially if you’re only tweaking certain page elements.
