Creating a prompt with custom dimensions
Configuration guide for setting custom dimensions on Recurly Engage prompts using Custom CSS.
How can I create a prompt with custom dimensions?
You can override the default size by adding CSS rules in the Custom CSS section of the prompt Editor. For example, to set a popup to 550 × 420 px:

.outer-modal {
width: 550px !important;
height: 420px !important;
}
Notes:
- Use
!important
to ensure your dimensions take precedence over default styles.- Test in Live Preview to verify your custom sizing behaves correctly across devices.
