HTML is the code used to create websites based on this language. Due to its huge prevalence and universality, HTML is the foundation of the current Internet and its peculiar foundations. The more professional name refers to the form of its notation, because it is “hypertext markup language”, which allows you to give elements, references to files or databases, resulting in the ability to generate very complex, extremely professional websites. With the help of HTML language there is a chance to change the appearance or format of each website. Due to the fact that it is an open language, no entity exercises power over it, which gives the possibility of continuous development and making possible corrections. Without the HTML language the internet as we know it would not exist.
