'Meetup' is a free One Page HTML template suited for promoting an event. Sections include intro overview, speakers, multi-price ticket options, event schedule (with day switcher), a contact form and a Twitter feed. You'd have to integrate those Buy buttons into something like PayPal, Gumroad or Shopify. Overall the design is fairly basic - I actually quite like speaker section - but a great starting point to announcing your event on low budget.
Today I’m very happy to introduce you to our first freebie. It’s a Meetup, a free One Page responsive bootstrap template. Which you can use as an event website, personal portfolio, etc. Meetup is elegantly designed and coded with one of the best front-end frameworks, which is Bootstrap.
