There are two different ways to influence the look and feel of the payment page: by using either the static template or the dynamic template.
In the static template, only the text colour, background colours and font type can be customized. The following parameters can be used for changing the layout. Not all of these parameters are available for all accounts.
The logo is only used for production accounts, not for test accounts.
With the dynamic template it is possible to customize the entire design of the payment page using a template and cascading style sheets (CSS); it is not, however, possible to modify the text size or the contents of this page, since we use a standard page for all the merchants.
If you use CSS you should host the file on a secure server to avoid security warnings. For production accounts the CSS can be hosted by us using the Logo hosting option. Unfortunately we cannot provide this service for test accounts. This ensures that your customer has all the information needed to effect his online transaction.
Please refer to the integration documentation for more information on customizing the payment page and using style sheets.
