You can customize the UI/UX of your website as per your requirement. We provide different options to customize the UI/UX of your website, which include Visual Designer, Template Editor and BYOD Engine.
However, there are few restrictions, when it comes to making any changes to payment related pages or payment popup window. We do not allow to make any customization to such pages due to security concerns. In the payment popup window users type their credit card number and other sensitive payment related information. If we allow changes to such pages, then anyone can hack all the sensitive information about the users (i.e Credit Card number, CVV code etc.).
