One HTML Page Challenge

The goal is to create anything you want within 1 single html file. Practice your skills with the barebones of web development. How creative can you be with such restrictions?

View Submissions


  • You must write all of your code in 1 single HTML file.
  • Your file must be less than 1mb (measured by the file size on github).
  • You cannot import any external files (this will be checked by looking at the network tab in chrome).
  • Due to the nature of hiding lots of funtionality behind APIs, you cannot have any incoming network requests.
  • You are allowed to use libraries, however the library must be hard coded into a script tag and still must fit under the 1MB file size. (I suggest using a cdn and replacing with hardcoding the minified library at the end, or use JSCompress).
