Why HTML is foundational in a web-enabled world

HTML is a markup language heavily utilized for creating web pages and web applications. HTML, when combined with JavaScript and CSS, has become a milestone for web development. One of the useful aspects of HTML is, it can embed programs written in a scripting language like JavaScript, which is responsible for affecting the behaviour and content of web pages. CSS inclusion would affect the layout and appearance of the content. The basic building blocks of any HTML pages are HTML elements. A structured document can be created with the help of structural-semantic text like heading, paragraph, list, link, and other items. Browser indeed does not display the HTML tags but utilize them to interpret the content of the page. One needs to study various tags and then understand their behaviour.
