HTML stands for HyperText Markup Language. It is the standard language used to create and structure content on the web. Every web page you see is built using HTML.
An HTML tag is the markup syntax like <p> or </p>. An HTML element includes the opening tag, the content, and the closing tag together — for example, <p>Hello</p> is a complete element.
<!DOCTYPE html> tells the browser which version of HTML the page uses. In HTML5, this declaration ensures the browser renders the page in standards mode and not quirks mode.
Void elements are HTML elements that do not have a closing tag because they cannot have any content. Examples include <br>, <img>, <input>, <hr>, <meta>, and <link>.
Semantic HTML uses meaningful tags like <header>, <nav>, <main>, <article>, <footer> that describe the purpose of the content. It improves accessibility, SEO, and code readability compared to using generic <div> tags everywhere.
Frequently Asked Questions
Common doubts about HTML Introduction

Always include <!DOCTYPE html> at the very top of every HTML file to ensure consistent browser rendering.

Indent your HTML code properly — nested elements should be indented 2 or 4 spaces to keep code readable.
Validate your HTML at validator.w3.org to catch errors early before they cause display issues.
