HTML is the standard language used to structure content on the web. It defines the elements on a webpage, such as headings, paragraphs, images, links, and more.

CSS (Cascading Style Sheets):
CSS is used to style and layout HTML elements. It controls colors, fonts, spacing, and positioning.

JavaScript is a programming language used to make websites interactive and dynamic. Unlike HTML (structure) and CSS (style), JavaScript adds functionality, such as:

• Responding to user actions (e.g., clicks, form submissions).
• Animating elements (e.g., slideshows, pop-ups).
• Fetching and displaying data dynamically (e.g., search suggestions, live updates).

Frontend Frameworks are libraries or tools that help developers build user interfaces efficiently by providing reusable components, structures, and utilities. They simplify the development process and enhance productivity.(e.g., React, Angular, Vue.js)

 Backend Development focuses on the server-side of web applications, managing data, business logic, and application functionality that works behind the scenes. It's responsible for handling requests, interacting with databases, and sending responses to the frontend. (e.g., Node.js, Django, Flask)

Web Design Principles are guidelines for creating websites that are user-friendly, visually appealing, and functional. Good web design balances aesthetics, usability, and purpose.
