Hey @tkwalker!
You can indeed style the organizer and venue pages however you’d like, and are encouraged to do so. We cannot offer support for customizations, however, so making custom styles and custom additions to the templates themselves is something you’ll mostly have to take the reins on.
With that being said, we’re happy to help as much as possible, and if you have one or two specific questions that we can help with let us know.
One great resource for making the sort of customizations you’re describing is our official Themer’s Guide, which you can find in full here → https://theeventscalendar.com/knowledgebase/themers-guide/
Give that a read and let us know if this helps!
Thanks,
George
