Note that HTML4 is quite out of date (from 1999), the most recent HTML standard from the W3C is here: https://www.w3.org/TR/html/ from 2014. However, if you plan to reference the standard to build software, the most useful spec is https://html.spec.whatwg.org/ which is what browsers and other applications follow.
