How to Add Custom Code to Justuno

This article will help show you how to add custom CSS and JS to a Justuno promotion

There are two ways to add custom code to the promotion and this article will help illustrate both to find the best option.


To get started, head to your promotions and access the design canvas.

Option 1: In the top right hand corner of the design canvas, click the grey "</> Custom Code" button and this will give you access to enter custom CSS or JS.

'Tab" options will apply to the entire window while "Pop up" options will only apply to the Justuno modal.

Option 2: This is to add inline styling for a specific layer only.

Select the layer you would like to edit and hit the 'Source' button. Once clicked the selected area will display the code for that section:

Friendly Note: We keep Justuno an open platform for those users who are technically savvy enough to implement the changes they want, we do not offer custom coding for clients.
