When you create your first event, you can see that HeySummit have a standard landing page. Now, you would like to make it your own.  

Quick start

Although you can change your primary, secondary and tertiary colours on HeySummit (under Event Setup > Settings > Branding & Content), editing your background colour is not currently an inbuilt feature we offer. 

To make this kind of change, you'll need some custom CSS (which can be entered under Event Setup > Settings > Branding & Content > Custom CSS). Please note that we can't provide technical support for custom CSS in either supplying code or troubleshooting code you've written, so only use this if you're sure of your coding skills or have the help of a developer.
