Introduction to HTML


HTML (HyperText Markup Language) is the backbone of the World Wide Web. It is a markup language used to create web pages. HTML defines the structure and content of a web page, allowing you to display text, images, links, and multimedia elements in a structured manner.

What is HTML?

HTML is a markup language, which means it uses tags to define elements on a web page. These tags are enclosed in angle brackets and are used to instruct web browsers on how to display content. For example, the <p> tag is used to define paragraphs, and the <img> tag is used to embed images.

Here's a simple example of HTML code that creates a basic webpage:

<!DOCTYPE html>
    <title>My First Web Page</title>
    <h1>Welcome to My Web Page</h1>
    <p>This is a paragraph of text.</p>
    <img src="image.jpg" alt="An example image">
    <a href="">Visit</a>

In this example:

  • <!DOCTYPE html> declares the document type and version of HTML being used.
  • <html> is the root element that encloses the entire web page.
  • <head> contains metadata about the page, such as the title displayed in the browser's tab.
  • <title> sets the title of the web page.
  • <body> contains the visible content of the web page.
  • <h1> defines a top-level heading.
  • <p> defines a paragraph.
  • <img> embeds an image.
  • <a> creates a hyperlink to another web page.

How Does HTML Work?

Web browsers interpret HTML documents and render them as visual web pages. When you visit a website, the browser fetches the HTML code, processes it, and displays the content as instructed by the HTML tags and attributes.

HTML is not a programming language like JavaScript or Python; it is a markup language focused on structure and presentation. To add interactivity and dynamic behavior to web pages, HTML is often combined with other technologies like CSS (Cascading Style Sheets) for styling and JavaScript for scripting.

Key HTML Concepts

  • Tags: HTML uses tags to enclose elements and provide instructions to the browser. Tags are written within angle brackets, such as <tagname>.
  • Attributes: Many HTML tags can have attributes that provide additional information or settings. Attributes are placed within the opening tag, like <tagname attribute="value">.
  • Elements: An element consists of an opening tag, content, and a closing tag. For example, <p> is the opening tag, content is the text or other elements inside, and </p> is the closing tag.
  • Nesting: HTML elements can be nested inside other elements. Proper nesting ensures the hierarchy and structure of the document are maintained.
  • Semantics: HTML tags have semantic meanings. For instance, <h1> represents a top-level heading, <p> represents a paragraph, and <a> represents a hyperlink. Using the appropriate tags enhances the accessibility and search engine optimization (SEO) of your web pages.

HTML is a fundamental skill for anyone interested in web development. It provides the foundation upon which web pages are built, and understanding its concepts is crucial for creating well-structured and visually appealing websites.
