Computer Programming :

So what is a computer programing language? How does it work? What does it do?

Below is the html file created by Claude.ai that displays the image of the solar system on the linked page.

HTML is an acronym that means HyperText Markup Language. It is read by a browser and used to display text, images, and all manner of other things on a web page.

Each browser may take the markup code and display the various texts and images slightly differently. There are organisations that try to standardise the protocols and various connections. Many browsers might innovate to make it faster, make it more secure, try to serve specific niches. Some might try to reduce advertising or harmful content. Nation states may want to prevent certain content and try to create their own browser protocols to prevent things reaching the eyes and ears of their citizens so may create their own standards.

So with that being said and one could elaborate further.

What is the code below and how does it work?

As said above a browser will take the code below and compile it into a code that can run on a computer.

HTML is primarily a standard by which a web browser can display items on a screen.

It can run various other packets of code within the browser which allows it to display animations, allow text, games or videos to be displayed.

When an html file is read one of the first things it looks for is the <!DOCTYPE html>

The browser will go through every line of code and check it against what it expects the code to look like and if it finds something it doesn't expect produce an error. The item may not display correctly and the programmer will need to fix the code in order for it to run correctly.

The next line <html lang="en">.

This <html> tag allows global variables to be declared. Such as lang which declares the written or spoken text being used or displayed on the page. This allows the browser to know what language is being used. So if your writing in Mandarin or even Scottish Gaelic you declare this here.

There is a list here. Where you can see that gd is the code for Scottish Gaelic.

So if your writing Scottish Gaelic then declare that here and the browser will adjust to suit. The html file just treats text as text. But the browsers can treat the text differently be able to translate the text from the language of the written text into the viewers language for example.
