You can customise the welcome banner by adding your own background image. If no image is supplied, it will default to the grey box.

The welcome banner is responsive across all devices and does not maintain a consistent aspect ratio, so when selecting an image for your banner you should keep in mind that the edges may get cropped on different screens.

You should supply a high-resolution image, long rather than tall, with the recommended dimensions of 1,500px × 500px.

You will need to have your image hosted under a URL.

To set the image in the welcome banner, ensure you are on the Title Level in the Partica dashboard and click the CUSTOM CSS EDITOR tab:

Create a new line and paste in the following code, replacing the image url with your own: 

.container main#content #flipbook-cover {background-image: url('https://www.imageURL.jpg'); background-size:100%; background-position: center; background-repeat: no-repeat; color: #ffffff; font-family: 'Roboto', cursive; font-size:1.145rem; font-style: normal; }
.container main#content #coverImageSection {background-image: url('https://www.imageURL.jpg'); background-size:100%; background-position: center; background-repeat: no-repeat; color: #ffffff; font-family: 'Roboto', cursive; font-size:1.145rem; font-style: normal; }

Click Save and Publish.
