Front end for a content-only one-page website

I am looking to have a one-page website for an event built. I just need the HTML/CSS/JS and will edit the content and host on my own. It is mostly content, but there is a Google Maps integration.

The only complex interaction is the mobile version of the schedule, which needs to be operable both by swipe gestures and by using a tab system. I can provide a prototype of the interaction built in Axure.

I will provide pixel-perfect designs and documentation in Zeplin or InVision. I will provide all image assets and icons. I am using Google Fonts. I am open to provide as much documentation as you need.

Animation would be appreciated, but is not essential. I can provide GIFs or MOVs of this as well.

The website needs to:
- Be responsive across 4 breakpoints. I'm using an adaptation of the Material Design responsive grid. If Bootstrap would make it easier, I am open to adapt the design.
- Be WCAG 2.1 compliant. The design already fulfils the relevant success criteria, but the code needs to be fully accessible to assistive technologies.
- Be compatible with all modern browsers. However, all content should still be readable even if users don't have CSS or JS active (or use their own CSS).

I have uploaded the Desktop version for reference, but will create mock ups for the 4 breakpoints. There is still some content missing, but I will provide placeholders. Once I have the final content, I can change it on my own.
