HTML (HyperText Markup Language) is the foundation of web development, enabling developers to create structured documents for the web. Whether you're a beginner or looking to refresh your knowledge, understanding HTML tags and attributes is essential. In this guide, we'll dive deep into the basics and provide practical examples to help you get started.
What are HTML Tags?
HTML tags are the building blocks of HTML, used to create and structure elements on a webpage. Tags are enclosed in angle brackets, like <tagname>. Most tags come in pairs: an opening tag (<tagname>) and a closing tag (</tagname>). The content between these tags is what gets affected by the tag.
Basic Structure of an HTML Document
Here's a simple example of an HTML document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First HTML Page</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text on my website.</p>
</body>
</html>
-
<!DOCTYPE html>: Declares the document type and version of HTML. -
<html>: Root element of an HTML page. -
<head>: Contains meta-information about the document. -
<title>: Sets the title of the webpage (appears in the browser tab). -
<body>: Contains the content of the webpage, visible to users. -
<h1>: Defines a top-level heading. -
<p>: Defines a paragraph.
Common HTML Tags
Here are some commonly used HTML tags:
Headings
HTML provides six levels of headings, from <h1> to <h6>, with <h1> being the highest level.
<h1>Main Heading</h1>
<h2>Subheading</h2>
<h3>Sub-subheading</h3>
Paragraphs and Text Formatting
<p>This is a paragraph.</p>
<strong>Bold text</strong>
<em>Italic text</em>
Lists
HTML supports ordered and unordered lists.
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<ol>
<li>First item</li>
<li>Second item</li>
<li>Third item</li>
</ol>
Links and Images
<a href="https://www.example.com">Visit Example.com</a>
<img src="image.jpg" alt="Description of image">
What are HTML Attributes?
Attributes provide additional information about HTML elements. They are always included in the opening tag and usually come in name/value pairs like name="value".
Common Attributes
href for Links
<a href="https://www.example.com">This is a link</a>
src and alt for Images
<img src="image.jpg" alt="Description of the image">
class and id for Styling and Scripting
<p class="text-muted">This is a paragraph with a class attribute.</p>
<div id="uniqueElement">This div has a unique ID.</div>
Boolean Attributes
Boolean attributes, such as checked, disabled, and readonly, don't require a value.
<input type="checkbox" checked>
<button disabled>Can't click me</button>
