Trying something creative in fluid engine

Hi everyone

I've had fun/frustration building this prospectus mini-site in fluid engine and trying to make it really creative. I thought I'd share since I was looking for inspiration at the start of this project and couldn't find that many examples yet. I'm a creative dabbler not a pro, and this is my first site with fluid engine so would be very happy for any feedback.

The good:
I found some stuff really nice to use, especially the text sizing and block layering, and I love the control of editing for mobile separately. This site looks so much better on mobile than I've managed before with the old editor.

The bad:
Some stuff seems glitchy and annoying. Some text 'flickers' on mobile, the carousel pictures don't load quickly. In the editor, once my page started getting long, it leaps all over the place when you hit edit, rather than keeping to your place. There's also weird side scroll background thing going on too which I think is from the section dividers code I used.

There's a bit of CSS - custom header font, some section dividers (thanks Chris Schwarz-Edmiston), some video block tweaks (thanks @joseph81), a couple of words made vertical in mobile, but as far as I could I've tried to exploit the in-built features.

Removed the CSS for the section dividers for now to fix glitching
