Gawddamn CSS and floaties

Okay so, I've already made a forum post regarding my cursor issue, which I fixed now... and I fixed everything else I wanted to fix, so I can use my old layout as a placeholder for now :,D (bit of an eyestrain warning, though, I'm sorry)

AND NOW I HAVE A DIFFERENT PROBLEM 😭

I fixed my floatie issue... but it doesn't show up on mobile at all. I have no idea why, since like I probably mentioned before (if not here then in forum), I copied my old layout from my other profile, which, when I open it in webview, it still shows up- (yes, I didn't move it to fit the actual profile, it's just on the site, but even when I just left it in the corner where it was, it just didn't show up...)

NOW, my question would be... is it a technical limitation as to why floaties don't show up on the mobile web/mobile web app? (Doesn't work on either) or is it just something that's missing in my code? If anyone actually has floaties that show up on mobile, could you tell me how you set yours up?
