On one hand, it doesn't make sense to be talking about CSS and web design when we are talking about _policy_ changes. I'm sure if you go back to when Reddit first released the new frontend, you would fine all the CSS discussions you look for.

On the other hand, lots of discussions are also happening around design and accessibility. Reddit's official app has bad design, including many dark patterns and terrible accessibility and performance. This has been discussion alongside the policy changes from day one.
