I can’t point my finger at it, but something really feels off about the layout of this page. A bunch of different spacing sizes mashed together, maybe? Doesn’t look good for a design token library website. Love the idea though!
I think it is that the elements alternate in height between the left and the right columns, creating a weird kind of feeling of instability as you move down the page. The vertical rhythm of the layout creates a feeling of unsettledness and disease.
I thought so too, tried putting a max width on the body and centering it. Ended up looking substantially better to my eye.
