Design your perfect checkout with custom styles.
Every checkout has the ability to have custom CSS under the Design tab in the checkout editor.
Custom CSS will only show on the published checkout, so when testing styles make sure to look at the public-facing checkout.
We intentionally add ID and class to the HTML markup on checkouts to make it easier for you to pick and choose where you’d like to apply styles. Your developer should have no issue finding the appropriate ID and class to make any changes.
