What is the best sequence to write code with HTML CSS and JS

And I learn when I have 13 years old that was HTML, CSS and JavaSCript, but today they don    t show a precedency for it, adn today I more than convinced that the sequence is important and let's see why:

You writing first the content you gonna, of course that if you are making a simple copy you don't need any senquence the sequence is a work manner and not to it work of course, so you write first the HTML that is the text of the document, that you are creating, if you write the CSS first you don't gonna even see the what make with the document because without the HTML the document is empty so the only thing you gonna see is the background of course. So with the HTML text, video also is in HTML and the Music is also HTML. And the Js for last because the buttons and the the empty fields that you gonna interact is put with HTML and the Js use the HTML buttons and entries, to give interactivity with the Js, if you started with the Js you gonna write buttons and you even cant' see if works, because you have the code about the button but the buton isn't there ohh!!! So you with HTML put the text, the videos the forms and buttons, istilize it all with CSS and after code with Js, because with HTML and CSS you have a good looking forms and buttons that doesn't make nothing, and CSS is important came before JS because before code you have a picture of your work you sometimes don't do a mockup to represent your work? So with the page with the final appearance that will help you to relize what you need to do with Js of other way you gonna after make the Js and making the CSS for least relize that you code doesn't fit, that you make completely mistake in the code and you gonna do all again right in the code that is to be the hard work in almost all the cases, of course that you don't need code to do a document but code is the hard work and the CSS is talent for art, and good taste, and creativity, and JS could be a very hard work to start all over, because you don't do it for last.
