Understanding the Differences in Web Development
Introduction®
In the world of web development, three key technologies—HTML, CSS, and JavaScript—work together to build interactive, user-friendly websites. Whether you are a beginner or an experienced developer, understanding the differences between these technologies is essential.
HTML (HyperText Markup Language) is responsible for structuring the web page.
CSS (Cascading Style Sheets) handles the visual styling.
JavaScript adds interactivity and dynamic features to the website.
In this guide, we will explore each technology, compare their differences, and demonstrate how they work together to create functional web pages.
