HTML: The basics of HTML

Every day we look at dozens of web pages and read texts on them that are rendered as though they were in a magazine. These pages are hypertext - a system of web pages that can be navigated using links. A language, HTML, exists to implement this system.

HTML stands for HyperText Markup Language. By its function, HTML is a set of rules by which the browser distinguishes headings from lists, tables from pictures, and so on. HTML appeared in 1993 and was intended to standardize the rules for displaying text within web pages.

Even this page is text marked up using HTML and processed by the browser. Technology has come a long way, but the concept of using HTML to mark up text has remained unchanged for many years.

Here is an example of HTML markup:

  <h2>Code Basics</h2>
    Code Basics - free hands-on programming lessons for people
    starting from scratch.
    If you are a complete beginner and want to learn the basics - variables,
    strings, loops, functions, etc., then Code Basics is for you.

Don't be intimidated by all the confusing words and symbols - by the end of the course, you'll understand how the markup above works, and you'll learn how to use this markup on your own pages. Note that the whole essence of the markup above is text. The rest are auxiliary elements to display the text where it was conceived to be by the designers and/or developers.


Copy the HTML and paste it into the editor on this page

<h1>Hello, World!</h1>
The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨

Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.

My code is different from the teacher's one 🤔

It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.

In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.

I've read the lessons but nothing is clear 🙄

It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.

By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
