How to change the post-purchase page font
Overview
The post-purchase page is drawn by Shopify checkout, so it uses your checkout's style, including its fonts. XB: Post Purchase Upsell has no font setting and no custom CSS, because Shopify does not allow custom CSS on checkout pages.
Steps
- In your Shopify admin, go to Settings > Checkout.
- Click Customize to open the checkout editor and change the typography of your checkout.
The new font applies to your checkout and to the post-purchase offer.
To change the text size or style of the offer instead, use the size and style settings on the Appearance step, for example Header title size or Product title style. See How to customize the post-purchase page.
