HTML, CSS, and JavaScript are three essential technologies used in web development. They work together to create dynamic and interactive web pages. HTML provides the structure and content of a webpage, CSS adds style and visual enhancements, while JavaScript adds interactivity and functionality. In this article, we will explore how these three technologies work together to create modern web experiences.

HTML: Structure and Content

HTML, or Hypertext Markup Language, is the backbone of web development. It defines the structure and content of a webpage using various tags.

CSS also supports the concept of cascading, where styles can be inherited from parent elements or overridden by more specific styles. This allows for consistent styling across multiple pages and easy maintenance of stylesheets.

JavaScript is a programming language that adds interactivity and functionality to web pages. It allows web developers to create dynamic and interactive elements that respond to user actions. JavaScript can be used to validate forms, create animations, handle user input, and much more.

JavaScript works by adding scripts to HTML documents. These scripts can be placed in the `
