The Code Injection field allows you to modify css elements, drop in pixels and other scripts. We recommend adding and testing injections ahead of your event so you can make tweaks if needed. There is about a 5 minute cache so please allow at least 5 minutes for the updates to take effect.
Note that this section should be used by someone who has experience adding custom code. Maestro is not responsible for reviewing or advising on 3rd party code injections.
