Where can you program a website yourself (write HTML and CSS code yourself)?

That’s what happens with HTML

No. For HTML, the document is read and then displayed by the browser. With every simple Hello world program, you use an instruction to output a text. In HTML or CSS, you do not directly enter the program flow of the browser.

With links, IF / ELSE can be easily generated

No, it can’t. Linking causes a browser to load and display another HTML document. More logic isn’t behind it, and there’s no falling distinction at all.

(Fast) All programming books start with Hello WorldProgramme. It is a program and I can also convert it into HTML.

No, not at all. Do not change what the browser does and displays with a program. Just because you can get the browser to display “Hello World”, you did not create a program. You don’t have it when you’re hacking in Word “Hello World”.

In a way, you will naturally control the output of the browser through the HTML source text. Nobody doubts that. But you don’t write a program.

and more is not necessary for a simple program!

If the program is to do something meaningful, yes. Then you need more. In addition, as mentioned, you give a direct instruction in a program, for example by a print function to draw a string on the screen. Internally, the programming language then needs at least the concept of data types, functions and a program flow.

While in HTML you will write everything you write, unless it is in special tags, also lands on the screen because it is just a document.

It doesn’t make it programming anyway. With an MP3 file, you also say what sounds should be played at what time. You also set up in a video process. Nonetheless, nobody says programming.

A link also does not represent a sequence. I can click whatever I want and then just land on another page. I also use the keyboard to tell a text program which letters it should write into the document. This is not programming either.

You can prescribe in CSS that certain actions trigger certain processes, but this is not programming.

Program texts of programming languages are executed either directly interpreted, instruction for instruction and you have full control over the program flow. Or they are compiled in machine code, which are then executed when the program is called up.

The writing of documents – and HTML documents are now documents – is not programming. This is strictly differentiated in computer science. If you use JavaScript, it’s something else.

HTML and CSS do not provide control structures, no data types, you have no options to write algorithms yourself.

HTML and CSS were originally developed to define the structure and design of websites. In contrast, programming languages are more aimed at enabling general calculations, processing of data and controlling processes.

This distinction is also not doubted in specialist circles.

Laienhaft is still often called programming because you can say that you have already programmed. Factically, however, it is not true and it is not bad and does not devalue the code in HTML/CSS.
