There are multiple examples of incoherent UI components across the https://nextjs.org/learn course.

For instance, I've attached a screen recording showing a large white button with missing text. Upon clicking, the browser scrolls to 0, and upon inspection in browser tools, you will actually find the button actually contains a "placeholder" string inside the innerHTML. This is not visible.

In the same screen recording, you also notice that buttons lack padding, which is inconsistent with the rest of the site.

While none of this is a blocker for me, per se, there is a clear opportunity for improvement.

I am happy to flag this through a different channel, but I'm not entirely sure which channel is most appropriate. Trying this one first.
