What is HTML
Ever wondered how websites are built? It all starts with HTML. This guide will teach you the essentials of HTML, the language that gives structure to every webpage you visit.

Step 1: The Client-Server Conversation
Your web browser (the client) sends an HTTP Request to a server asking for a webpage. The server finds the HTML file and sends it back in an HTTP Response.

What Exactly is HTML? A Beginner's Guide
Welcome to the world of web development! If you're new here, you've probably heard of HTML. But what is it, really? Let's break it down in this blog-style guide.
The Skeleton of the Web
HTML stands for HyperText Markup Language. That might sound complicated, but the concept is simple. Think of a house. Before you can paint the walls or add furniture, you need a solid structure—the foundation, walls, and roof. HTML is the skeleton of a webpage. It provides the basic structure and content.
It's not a programming language; you can't use it to do complex calculations. Instead, it's a markup language, which means it uses tags to "mark up" or describe the content on a page.
Tags and Elements: The Building Blocks
HTML uses special keywords called tags, which are enclosed in angle brackets (e.g., <p>). These tags are the building blocks of your webpage. Most tags come in pairs: an opening tag and a closing tag.
<h1>for a main heading<p>for a paragraph<a>for a link<img>for an image
An element is the complete package: the opening tag, the content inside, and the closing tag. For example:
<p>This is a paragraph element.</p>What are Attributes?
Attributes provide extra information about an element. They are always included in the opening tag. For example, the <a> tag for a link needs an href attribute to know where to link to:
<a href="https://www.todotutorial.com">Visit TodoTutorial</a>Here, href is the attribute.
A Basic HTML Document
Every HTML page has a standard structure. Here’s what a very basic one looks like:
<!DOCTYPE html>
<html>
<head>
<title>My First Webpage</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is my first webpage.</p>
</body>
</html><!DOCTYPE html>: This tells the browser it's an HTML5 document.<html>: The root element that wraps everything.<head>: Contains meta-information about the page, like the title. This part isn't visible on the page itself.<body>: Contains the content you actually see on the page, like headings, paragraphs, and images.
Key Takeaway: HTML is the foundation of every website. It gives content structure and meaning. Once you have your HTML skeleton, you can use CSS to style it and JavaScript to make it interactive.
HTML & Web Glossary
- HTML (HyperText Markup Language)
- The standard markup language for creating web pages and web applications.
- Tag
- The building blocks of HTML, enclosed in angle brackets, used to create elements. Example:
<p>. - Element
- A complete HTML structure, consisting of an opening tag, content, and a closing tag. Example:
<h1>Title</h1>. - Attribute
- Provides additional information about an HTML element and is always specified in the start tag. Example:
hrefin<a href="...">. - DOM (Document Object Model)
- An in-memory, tree-like representation of an HTML document created by the browser. It allows scripts to dynamically access and update the content, structure, and style of a document.
- Semantic HTML
- The use of HTML markup to reinforce the semantics, or meaning, of the information in webpages rather than merely to define its presentation. Examples:
<article>,<nav>,<header>. - DOCTYPE
- A declaration at the top of an HTML document that tells the browser what version of HTML the page is written in.
- Client
