## Pop-up

For pop-ups we recommend that you create a number of templates that implement your brand guidelines for pop-ups, with different button types (e.g., two-button CTA). On those templates, you can set brand colours as outlined below. First navigate to the templates section (**Content > Templates**) and select on-site message:

Once in the editor select pop-up and click on the paint brush to edit the colour palette used for key components.

This graphic illustrates how settings map to the various components of the pop-up:

Once you have templates setup with the default colour values, you can add images when creating individual pop-up campaigns.

### Image dimensions

- **Dimensions**: The maximum image size is 2000x2000 px. The image height setting (auto by default) will resize the displayed image proportionately.
- **Valid image formats**: PNG, JPG (JPEG), GIF (animated too)
