Html Basics
HTML language is not only universal, but also one of the easiest for beginners to learn. It is the foundation of every website.

If you know how to code in HTML, you will be able to create and structure web pages. To give them a sharp and dynamic look, you should combine HTML elements with CSS and JavaScript. Before that, you should get familiar with HTML basics and learn to use tags.

Tim Berners-Lee created HTML in 1990 and based it on the Standard Generalized Markup Language (SGML). The main principle of HTML basics is surrounding text with angle-bracketed tags to apply a chosen element.

What does HTML stand for? HTML is an acronym for Hypertext Markup Language. It is meant to help people structure and format content so that Internet browsers would display pages correctly. Using HTML alone won't be enough to make your websites appealing. You should learn the Holy Trinity: HTML, CSS, and JavaScript.

Before you start learning HTML language basics, you have to keep in mind the importance of proper tag construction. Tags are divided into different categories according to their purpose:

  • The root element
  • Document metadata
  • Sections
  • Grouping content
  • Text-level semantics
  • Edits
  • Embedded content
  • Tabular data
  • Forms
  • Interactive elements
  • Scripting

A regular HTML tag consists of only a few components. It begins with an opening tag and ends with a closing tag which has to contain a forward slash before the tag name. Less than (<) and greater than (>) angle brackets are used to enclose each tag.

Tags that define empty elements are self-closing: they do not require a closing tag. Still, that is an exception - not a rule. Most tags won't work properly if you do not add a forward slash to the closing tag.

Why You Should Learn HTML: Purpose and Use

After learning HTML basics, you will be able to perform many changes to your page:

  • Content structure: make your websites easy-to-read and improve user experience by dividing texts into paragraphs, lists, quotes, and headings.
  • Graphics: add images, music, video, or interactive content into your website.
  • Meta tags: improve the SEO rating and overall findability of your website by telling search engines which keywords are related to your website.

 <h1>Heading for the content below</h1>
 <p>Text text text</p>

  • The following tutorials cover various tags you can apply to your documents: elements, headings, paragraphs, and so on. We also provide code examples for you to practice the hypertext markup language!
  • Speaking of code examples, make sure to click the Try it Live button when available. Our code editor will allow you to make changes to the code and analyze the results instantly. You can find this button under most code examples.
  • If you are struggling to master the advanced features of HTML coding, we suggest you continue learning with our interactive and video courses. You will find user-friendly tutorials that are designed for beginners that are just starting to grasp the HTML language basics.
  • HTML should not be the only language you decide to learn. We provide detailed tutorials on CSS and JavaScript as well. The difference between HTML and CSS is that the latter is used for styling. Adding JavaScript allows you to control the behavior of elements.

What You Will Learn

Our tutorial is divided into separate parts, discussing different aspects of HTML basics. We start with the fundamentals and move on to more advanced topics, so you get to know all the essential principles before you start building complex structures.
