What is HTML?

HTML (HyperText Markup Language) is used to structure and format the content of websites on the World Wide Web. Web Developers use it to create a skeleton of modern websites and web apps.


What is HTML?

In simple words, HTML is the primary building block to create and structure website content.

Let's see what HyperText Markup Language means.

  • HyperText
    HyperText is a way of organizing text that allows the reader to easily navigate and access related information. It takes the reader to a different part of the same web page, or to a different web page altogether.
  • Markup language
    A markup language is a computer language that is used to add structure and formatting to a text document. Markup languages use a system of tags to define the structure and content of a document. These tags are interpreted by a program or application to display the document in a specific way.

Example of HTML

Let's see a simple example of HTML.

<!DOCTYPE html>
<html>
    <head>
        <title>programiz</title>
    </head>
    <body>
        <h1>HTML Tutorial</h1>
        <p>You'll learn about HTML.</p>
    </body>
</html>

Browser output

A simple HTML example

In the above program,

  • <!DOCTYPE html> - defines that this document is an HTML document
  • <html> -root element of an HTML page which encloses all other elements in the HTML page
  • <head> - contains information about the page, such as the title and metadata
  • <title> - specifies a title for the HTML page which is shown in the browser's title bar
  • <body> - defines the main content of the page and is a container for all the visible contents, such as headings, paragraphs, lists, etc
  • <h1> - defines a heading
  • <p> - defines a paragraph of HTML document

How HTML works?

HTML works by defining the structure and content of a web page using a series of tags like <h1>, <p>, etc. Each tag has a meaning and can be used to define the purpose of the content it encloses. For example,

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width">
        <title>Programiz</title>
    </head>
    <body>
        <center><h1>Programiz</h1></center>

        <p>

        <p>
        <button>Join for free</button>
    </body>
</html>

Browser output

A simple HTML example

As you can see, a web browser reads HTML tags and displays them on the browser by interpreting their meaning. In the above code:

  • <h1> tag - displays the content inside it as a heading
  • <p> tag - displays the content inside it as a paragraph
  • <center> tag - displays contents inside it at the center of the page

How to create and run an HTML file?

You will need a text editor and a web browser to create and run an HTML file on your computer. You can follow the following steps to create and run an HTML file on your device.

  1. Open a text editor. There are many text editors available, such as Notepad (on Windows) or TextEdit (on macOS).
  2. Open text editor
  3. You can now start writing HTML code in your text editor. Here's a sample code you can type:
  4. Type HTML Code
  5. Save the file as index.html (or any other name with the .html extension) in your desired location.
  6. Save HTML Code
  7. Open the HTML file in a web browser. You can do this by double-clicking the HTML file in the location where you saved it, or right click on your HTML file and choosing open.
  8. Open file in web browser
  9. The HTML file will be displayed in the web browser, and you can view the content of the file.
