Behold the "One HTML Page Challenge" -- to build a one-page site using just the code in a single html file: "Practice your skills with no assistance from libraries, no separation of files, and no assistance of a modern framework."
There are a just few entries so far, but they're pretty cool -- like this one that creates a slowly-growing ant colony in ASCII, or this racing game, or this quiz to see if you can identify the correct name of a color.
I dig the constraints here -- all code in one file, no outside code libraries -- because it really honors "view source" culture.
When I was interviewing developers for my latest book Coders, all the ones who grew up during the late 90s and early 00s web talked about how powerful view-source was in teaching themselves to code and make stuff online.
So, projects like this one-page challenge are awesome, because the whole goal is to encourage the writing of web-site code that's more legible and tractable. If you view-source any of the entries, some might be a little complex for newbies, but if you spend enough time walking it through, you can figure out what's going on. Sites like Glitch or CodePen are other terrific examples of rebooted view-source culture too. We need as many resources like this we can get!
