HTML = Hypertext Markup Language
Lol
But as for OP:
I'd suggest getting the basic syntax of a common and widely used language, like C++ or Java (both of which have promising futures in the terms of the programming world). After that, you'd better understand other languages and have sort of a base knowledge of what is happening.
It really depends what field you want to get into, because programming encompasses a wide variety of jobs and careers.
I'm so happy you are putting your mind to this and making it a reality! All of the power to you!
HTML is a Markup language it's not considered a "Programming Language" as PHP isn't either when compared to Java or C++
