Edit your theme code

Premium feature available on paid plans

If there are more advanced changes you want to make to your design that aren’t included in our built-in theme editor, you’ll need to dig in to your code, check out a third party theme, or hire a designer.

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.

CSS-wise, it’s best to override existing styles at the bottom of Customize Design > Advanced > CSS instead of editing it directly, especially if you’re only tweaking certain page elements.

Also, feel free to include custom Javascript, stylesheets, or font files. Just make sure they’re hosted externally, as we don’t offer file hosting.

Third-party themes and resources

If none of our built-in themes strike your fancy, but you don’t have any coding experience, you may want to check out other pre-made themes or code add-ons from third party builders: WeTheme, Theme Fiend, and Greg Scharf.

Each theme provider will give you their own set of instructions for applying their design to your shop.

If you’re looking to hire some outside help, here are some designers/developers you might check out:


  1. Head to the Account area in your admin.
  2. Click Customize your design.
  3. Click the Advanced tab.
  4. Choose the page you want to edit.
  5. Click the Custom button to make changes, or click Default to revert to the page’s original theme code.
  6. When you’re finished, click Done and Save.
