In previous years when helping student with webdev: I used to find many were amazed when I showed them you could just read the source code of other sites (including CSS) to find out how they have done things. The idea of everything being in plaintext is not something they expect, why would they when everything else is opaque? Especially the big frameworks they come to me with 😐 so many misunderstandings and confusions were from them starting with these.

I'm glad the web is still mostly plain and I'm glad HTTP 1.1 is not going away, these things are vital to the long term health of the system. If you cannot understand something then you are doomed to repeat mistakes. Complex websites often last only a few years before being remade.

The CSS naked day website has a list of sites that have participated. I'm going to click a few random ones and see where its takes me.
