The Foundation: What is Web Design and Development?

What is Web Design?

Web design refers to the visual aesthetics and usability of a website. It includes elements like:

• Layout

• Color scheme

• Typography

• User interface (UI) design

• Responsive design

Great web design is user-centric. It ensures users can navigate a site intuitively and find information easily.

What is Web Development?

Web development is the technical side of building a website. It involves:

• Writing code (HTML, CSS, JavaScript)

• Server-side scripting (PHP, Python, Node.js)

• Database management (MySQL, MongoDB)

• CMS integrations (WordPress, Shopify)

• Security and performance optimization

Together, design and development make a website both functional and aesthetically pleasing.

User experience (UX) is paramount. Sites must be:

4. Visual Hierarchy

Use size, color, and spacing to guide users' attention. Headings, buttons, and CTAs should stand out clearly.
