Explain how the CSS helps in enhancing the design of a webpage.

CSS (Cascading Style Sheets) separates presentation from HTML content, so one stylesheet styles hundreds of pages consistently.

How it enhances design:

1. Consistent look — One style.css sets colours, fonts and header for the whole gov.np site; change once, all pages update.
2. Layout — Flexbox/Grid create responsive columns, menus and cards that fit mobile and desktop (mandatory under Website Directive 2078).
3. Readability — Line spacing, contrast and Nepali font (Nirmala UI) settings improve citizen reading.
4. Interactivity — Hover, focus and print styles without JavaScript. Example: a:hover { color: blue; }.
5. Types: Inline (<p style>), Internal (<style> in head), External (<link href="style.css">) — external preferred for reuse and caching.

Example: body { background: #f5f5f5; font-family: "Nirmala UI"; } table { border-collapse: collapse; } instantly cleans a raw HTML table.
