Everything between the homepage hero & the schedule on your home page can be customized. Keep in mind that there are a few required ads (FloHockey, Dash) that you must remember to incorporate, but otherwise you can make the homepage your own.
Navigate to /admin > Homepage > Modules (tab)
By default, modules may be closed. To expand & work on a module click on the + symbol next to the module.
You can move content modules up & down by clicking on the move up / move down buttons (make sure you save the page after you reorder a module).
All Modules display at 100% width on mobile devices, but you can control the width of most of the modules on desktop. There are a few modules that will always show at 100% width (social feed, ads, stats), and a few that may not look great displayed as a 1 column.
Your homepage (on desktop) is set up as three columns. If your first module is set to 2 columns then your next module needs to be 1 column. Otherwise, that module won't appear on that row & you will have a blank space to the right of the first module. Feel free to modify modules, publish them, and see how they interact on the homepage.
