While HTML and CSS are programming languages, they are really limited, and some people do not refer to them as actual programming language. You need to learn all the basics of any programming language(python,java,c++,javascript,etc) first. You have a ton of resources for this, personally i would recommend Youtube. Mosh Hamedi's tutorials on youtube were very helpful to me. You have google as well,just use that search bar. Goodluck! Akinpelu Gladness Oluwadunsin

Documentation!! It really cannot be overemphasized. This was a delight to read.👏
