Just HTML, SCSS and Vanilla JavaScript

Any feedback on the project is welcome, but I also have a question about semantic HTML.

I initially planned to use CSS grid to position elements in desktop layout, but to achieve that, I had to pull the image container outside of the <main> element. I wasn't happy with having just a random <div>, so I thought of changing it to <aside> but I thought that it wasn't the best choice either as it literally has no content in it.

I ended up just positioning the image absolutely which I think is the simplest solution here and I'm happy with it, but would love it if someone could comment on my <aside> problem, just so I know for the future :)

Thanks!
