This is a web app for hosting an online march. One can join the march by signing up with a username and password. The homepage displays a small square for each user. You can pick a color or image for your square. Each user can set a message that displays on rollver. Users can up/down vote other users. I set up a burrito march here.

I started this in summer 2019 and it's built with HTML, CSS, JavaScript, PHP, MySQL and Paginator.
