I'm curious why can't the html standard be defined in form of source code (of a parser and a render), rather than human language.
the trouble developers have to support many browsers is because of the implementation variations.
a recent issue I had on Edge is that if the border color is #FFFFFFFF, it is rendered as black, but on other browsers, this is white.
What if the standard itself is defined as a common source code, and not owned by any company?
the standard implementation could be a dumb one without any hardware acceleration. It only needs to define the correct behavior. Any customized implementation has to conform to it.
