HTML, short for HyperText Markup Language, is a markup language used in web development. HTML has been developed since the early days of the Internet, when there was a need for a way to present text and links online. HTML has undergone many significant changes and development has continued up to the present day.

The first version of HTML, HTML 1.0, was released in 1991. This version included only a few basic features, such as marking headings, text, and links.

The first website was published on August 6th, 1991 at the address 

http://info.cern.ch/hypertext/WWW/TheProject.html

, where it can still be found today. The website was created by Tim Berners-Lee, the developer of the World Wide Web (WWW).

The HTML code for the website looks like this:

In 1993, HTML 2.0 was released, which introduced tables and images.

In 1995, HTML 3.0 was released, which brought significant new features such as frames and style sheets (CSS).

In 1997, HTML 4.0 was released, which brought many new features, such as internal table borders, extension of style sheets, and improvements to forms.

In 1999, W3C published XHTML, which was the successor to HTML. XHTML combined the best aspects of HTML and XML, with the aim of making web pages more standardized and easier to process for computers.

In 2014, HTML5 was released, which is the latest version of HTML. HTML5 includes many new features, such as video and audio support, improvements to tables and forms, and many other features that make website design and development easier.

Development of HTML continues, and new features are regularly added. HTML is still an important part of web development, and it can be used to create all kinds of websites, from simple blog pages to complex applications.

What is HTML?

This course is an introduction to web development and focuses on the basics of HTML, CSS, JavaScript and backend systems. The aim of the course is to provide students with the necessary skills and knowledge to design, develop and understand simple web applications.

This course is an introduction to web development and focuses on the basics of building websites, namely HTML, CSS, JavaScript, and fundamentals of backend systems. The goal of the course is to provide you with the necessary skills and knowledge to design and develop simple full-stack web applications, as well as understand web applications made by others.

In the first part, HTML is studied, which is a markup language used in building websites.


The second part covers the basics of CSS, such as the use of style sheets, rules, selectors, and formatting. It also covers advanced features of CSS, such as animations and responsive design.

In the third part, we will study JavaScript, which is currently an incredibly important tool in both frontend and backend development, and thus also in cybersecurity and ethical hacking.

In the final part, we will learn how to build back-end systems using the Python Flask framework. You will learn the basics of back-end systems, such as using databases, authentication, session management, and access control.

You can do the course exercises on your own computer if you want, but each code example has a button that allows you to directly run the code in the browser and see what the page looks like or what the script prints. So you do not need to install anything, but you can if you want.

It is recommended but optional to create an account on replit.com service. In that case, you can just click "Fork" on the code examples to make a copy for yourself to play with
