HTML, or Hypertext Markup Language, is the foundation of nearly every website you visit. It’s the standard markup language used to create web pages, giving structure to content through elements like headings, paragraphs, links, images, and more.

Think of HTML as the blueprint of a website. It organizes and defines what you see on a page. Whether you’re reading an article, filling out a form, or clicking a button, HTML makes it all possible.

Alongside CSS (Cascading Style Sheets) and JavaScript, HTML is one of the core web technologies used to build engaging, functional websites.

How HTML works

HTML uses a system of "tags" to format and display web content. These tags tell web browsers how to interpret and present text, images, and multimedia within HTML documents. The HTML markup defines the structure of a web page, organizing elements like headings, paragraphs, and links so they appear correctly on different devices. Here’s a simple breakdown of how HTML works:

• Structure: HTML creates the layout of a webpage, like where the headers, paragraphs, and images go.
• Elements: Tags like < h1 >, < p >, and < a > define different types of content, from titles to links. Each element starts with an opening tag and ends with a closing tag (like < p > and < /p >).
• Attributes: Extra information added to tags, like image sources or link destinations, help shape behavior and appearance.

What HTML is used for

Hypertext Markup Language, HTML, plays a crucial role in web development, acting as the backbone of website content and structure. Here are some of its most common uses:

• Creating web page layouts: HTML arranges text, images, and multimedia on a page.
• Building forms: Elements like < input > and < form > help gather user data.
• Embedding media: Tags like < img >, < video >, and < audio > add rich visual and audio content.
• Linking pages: < a > tags connect different parts of a website or direct users to external sites.
• Organizing content: HTML creates clear, readable page structures with headings, lists, and tables.

How to add HTML to a website

Adding HTML to a site is pretty straightforward. If you're just starting out, following an HTML tutorial or browsing HTML examples can help you understand the basics. Here’s a quick step-by-step:

1. Create an HTML file: Open a text editor and save your file with a .html extension.
2. Write your HTML code: Add the basic structure and any content you want on your own web pages.
3. Open in a browser: Double-click the HTML file to view your page in any web browser.
4. Upload to a web server: If you want the world to see your own website, you’ll need to upload the HTML file to a hosting service.

You can also combine HTML with CSS for styling and JavaScript for dynamic behavior, creating a polished, interactive website.

Best practices for using HTML

To get the most out of HTML, keep these best practices in mind:

• Use semantic HTML: Tags like < article >, < section >, and < nav > make your code easier to read and improve accessibility.
• Keep your document structure organized: Use clear, nested elements for better layout and maintainability.
• Combine with CSS and JavaScript: HTML creates the foundation. CSS styles it, and JavaScript adds interactivity.
• Validate your code: Tools like the W3C Validator help catch errors and ensure your HTML follows web standards.
• Optimize for SEO: Use proper heading structures and meta tags to improve search engine rankings.
