HTML (HyperText Markup Language) is the standard markup language used to create web pages. It structures the content on the internet, allowing web browsers to interpret and display text, images, videos, links, and other elements.
1. What is HTML?
HTML is a markup language, meaning it structures content using tags. It doesn’t have programming logic like variables or functions (unlike JavaScript), but it provides the framework for webpages.
🔹 HTML files are simple text documents with the extension .html.
🔹 HTML works together with CSS (for styling) and JavaScript (for interactivity).
🔹 Every webpage, whether built with WordPress, React, or any other framework, relies on HTML.
