# Smallest possible […] file

This repository aims to collect the smallest possible syntactically valid files in different programming/scripting/markup languages.

It all started with [a blog post on the smallest possible HTML/XHTML files](https://mathiasbynens.be/notes/minimal-html)…

Pull requests welcome!
