So you want to be a web developer. In web development on the client-side, you have to majorly deal with 3 things: contents, style and logic.

HTML tutorial

What Is HTML5?

HTML is a markup language that stands for HyperText Markup Language. HTML5 is the latest version of HTML with the addition of some new tag and improvement to some existing ones.

HTML is the most basic language which is necessary if you want to learn web development. It is used to create core part of web pages like inserting text, images, videos, audios, etc.

It creates the basic structure of web pages using different tags and elements by nesting these inside each other creating a hierarchical tree-like structure.

It is to be noted that HTML a markup language, not a programming language and these 2 are very different things.

HTML is not considered a programming language because in HTML:

  • There is no way to store value
  • There no logic creation
  • There is no control system
  • There are no ways to repeat a task
HTML just enclose data and metadata within the elements and the elements tell the browser how to render or use the enclosed data.

Note: A Markup language is a type of language which is used for the presentation of different elements like text, image, audio, video, etc on computer screens.


How to start HTML?

In HTML we only deal with how to represent text, image, videos, etc on a webpage using the browser.

For this, we have specific HTML tags for each special task. Like for paragraph we have <p> tag, for image we have <img> tag and so on.

These tags with their content are known as HTML element. A web page consists of a series of HTML elements, which is nested in each other and enclose contents of web pages.

For example, look at the picture below how HTML elements nest each other and hold contents.

HTML sample code

HTML tell web browsers how to structure the contents in a web page. HTML tags are used by web browsers to interpret and compose text, images, audio, video and other different material into visual or audible web pages.

Example of HTML tags

If you want to display the message "HTML is a Markup Language" on a web browser then you will have to enclose the message in the <p> tag as shown below.

<p>HTML is a Markup Language</p>

The above code will read by the browser and the browser will display the message within the <p> tag on the screen.

HTML documents can be designed in simple notepads using the basic syntax required for a webpage and must be saved with an extension of either .htm or .html.
