What is HTML? A Complete Beginner's Guide to Web Development

HTML, which stands for HyperText Markup Language, is the fundamental language used to create and structure content on the web. Since its creation in 1991 by Tim Berners-Lee, HTML has evolved significantly, becoming an essential tool for any web developer. In this comprehensive guide, we'll explore what HTML is, how it works, and how you can start using it in your own web development projects.

What is HTML?

HTML is a markup language used to create the structure and content of a web page. Unlike traditional programming languages, HTML has no programming logic; instead, it defines elements and attributes that tell the browser how to display the content.

HTML elements are represented by tags, which usually come in pairs: an opening tag <tag> and a closing tag </tag>. Within these tags, you can place text, images, links, videos, and other types of content.

Basic Structure of an HTML Document

A typical HTML document has a basic structure that includes the following sections:

<!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Mi first HTML PAGE</title>
</head>
<body>
    <h1>Welcome to HTML</h1>
    <p>this is a paragraph in HTML.</p>
</body>
</html>

<!DOCTYPE html>: Declares the type of document and the HTML version.
<html>: The root tag that wraps all the content of the document.
<head>: Contains metadata about the document, such as the character set and title of the page.
<body>: Contains the visible content of the web page, such as headings, paragraphs, images, links, and more.

Common HTML Elements

1- Headings: Used to define titles and subtitles.

<h1>Level 1 Heading</h1>
<h2>Level 2 Heading</h2>

2- Paragraphs: Used to group blocks of text.

<p>This is a paragraph of text.</p>

3- Links: Allow you to create hyperlinks to other pages or resources.

<a href="https://www.example.com">Visit Example</a>

4- Images: Used to insert images into the page.

<img src="image.jpg" alt="Image Description">

5- Lists: Used to group items into ordered or unordered lists.

<ul>
    <li>Unordered list element</li>
    <li>Other element</li>
</ul>
<ol>
    <li>Ordered list element</li>
    <li>Other element</li>
</ol>

HTML Attributes

Attributes provide additional information about HTML elements. They are placed inside the opening tag and usually consist of a name and a value.

1- href attribute: Defines the URL of a link.

<a href="https://www.example.com">Link to Example</a>

2- src attribute: Specifies the path of an image.

<img src="image.jpg" alt="Image description">

3- alt attribute: Provides alternative text for an image.

<img src="image.jpg" alt="Image description">

4- Class attribute: Defines a class for the element, used to apply CSS styles.

<p class="style">Text with class</p>

5- Id attribute: Assigns a unique identifier to the element.

<div id="container">Content here</div>
