The Different Roles in Web Development
Web development isn't a single job; it's a field with specializations. Most developers focus on one of three main areas. Click the tabs below to learn about the distinct roles and the part they play in building for the web.
Front-End Development (The "Client-Side")
The front-end is everything the user sees and interacts with directly in their browser. A front-end developer is like an interior designer for a website, ensuring the layout, visuals, and interactivity are beautiful, functional, and user-friendly.
- Focus: User Interface (UI) & User Experience (UX).
- Core Technologies: HTML (structure), CSS (styling), and JavaScript (interactivity).
- Common Tools: React, Angular, Vue.js, Tailwind CSS.
Essential Skills for Web Development
Becoming a web developer requires a mix of technical and soft skills. The chart below illustrates the foundational importance of core technologies, which serve as the building blocks for more advanced tools and specializations.
Web Development vs. Web Design
Though often used interchangeably, web development and web design are two distinct disciplines. Design focuses on the look and feel, while development focuses on making it function. A great website needs both. Here's a breakdown of the key differences.

|---|---|---|
| Main Focus | Visuals, aesthetics, and user experience (UX) | Functionality, logic, and technical implementation |
| Primary Tools | Figma, Adobe XD, Sketch, Photoshop | Code Editors (VS Code), Frameworks, Databases |
| Core Skills | Color theory, typography, UI/UX principles, wireframing | HTML, CSS, JavaScript, server-side languages, problem-solving |
| End Goal | Create a beautiful and intuitive user interface | Build a fully functional and responsive website |
