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.
