Typically the Checkout page is not something that can be customized because it is pulling from a shortcode. That being said, there are some options that we can do and some things that we should not ever do.
Can Do
- Update Background Color
- Update Font Color
- Update Font Style
- Add Buttons/Text/Images to the page that are NOT unique to the customer or products
- Meaning if you add an image of a cat to your checkout page, everyone visiting the checkout will see this regardless of what is in their cart or who is checking out.
- Remove Coupon Options
- Add Custom Checkout Fields Via Plugin
- Include Add On Options Via Plugin
- Edit the Submit Order button text Via Plugin
Can NOT Do
- Remove Billing Fields
- This often prevents payment gateways from processing orders
- Remove Shipping Fields
- This will result in shipping calculations not running properly
- Add Product Images Unique to the Customer’s Cart
- Rearrange How the Content is Displayed
