How do I change the colors and fonts of my checkout page?

By default, the optimized one-page checkout that comes with your store is black and white. But that may not match your website’s color scheme. Don’t worry – you can change it!

Go to Storefront > Theme and click the Customize button next to your active theme. Click the icon that looks like a paint palette in the left navigation to access the theme settings. Then look for a section named Checkout Settings or Optimized Checkout. Click on that to configure the colors, fonts and other design-related checkout settings.

Don’t forget to publish your changes when finished.
