You can add CSS (Cascading Style Sheets) at both the Organisation and Event level, similar to the options for JavaScript. With this you can manage design and brand styling more effectively across multiple events using the organisation stylesheet, and can be further modified for a more unique look at an event, form or page level to suit your event needs. 

Event level – Applies to all forms within an event

Organisation level – Applies to all forms within an organisation

Order of execution for CSS follows the below sequence:

Organisation < Event < Form < Page

This is important to note when applying CSS, as your design will apply the last configuration in the sequence.
