Introduction to HTML


Web pages and web apps are often created and structured using HTML (HyperText Markup Language). It makes use of tags or components to specify the structure and content of a webpage. The foundation of all online development, HTML allows web browsers to display text, pictures, multimedia, and other content.

Key Concepts of HTML:

Markup Language: Not a programming language, but a markup language is HTML. It is made up of tags that "mark up" content on a webpage according to specific guidelines.

HyperText: This is the capacity to use hyperlinks to link to other web sites. You can make clickable links in HTML that take readers to other pages or specific areas of the same page.

Structure of an HTML Document:
A simple HTML document contains distinct tags that instruct the browser on how to understand the information and a well defined structure. The principal elements consist of:

DOCTYPE Declaration

The browser is informed that the page adheres to the HTML5 specification (the most recent iteration of HTML) by the declaration.

<!DOCTYPE html>


HTML Document Structure:

<!DOCTYPE html>
<html>
  <head>
    <title>Page Title</title>
  </head>
  <body>
    <h1>Hello, World!</h1>
    <p>This is a simple HTML document.</p>
  </body>
</html>


<html>: The root of an HTML document is the <html> element. It contains all other HTML elements contained within.

<head>: Metadata (information about the HTML content) such as the title, character set, and external resources (such CSS or JavaScript files) are contained in the <head> element.

<title>: describes the webpage title that appears in the browser tab.

<body>: The whole webpage's visible content, including text, photos, links, and more, is contained in the <body> element.
