A couple of things I noticed...

Mostly unimportant but I thought I'd record them and then do a PR when I have some time as a thanks for letting me clone...

• overflow: none; is not a thing - i.e. none is not a taken value here. You're probably looking for overflow: visible which is default or auto would work but this is 'let the browser decide'
• the manifest spec changed, so instead of a manifest.json file you want a marcusblog.webmanifest - should work with a rename as it's just the extension & still JSON. See https://github.com/Rumyra/blog-rumyra/blob/master/src/rumyrasblog.webmanifest

😆 Guessing I meant to do overflow: hidden;

Yeah, been meaning to sort the manifest but as I'm not aiming for it being a PWA app it's not been a high priority to sort out. 😁
