4. **Viewport Meta Tag:** Include the viewport meta tag in your HTML (“) to control how the page is displayed on various devices.

5. **Mobile-First Design:** Start your design with a mobile layout and then use media queries to enhance it for larger screens. This ensures a better experience for smaller devices.

6. **Relative Font Sizes:** Use relative units like em or rem for font sizes. This allows text to scale according to the user’s preferences.

7. **Testing:** Regularly test your design on various devices and browsers to ensure consistent performance and appearance.

8. **CSS Flexbox and Grid:** Leverage flexible box layouts (Flexbox) and grid layouts to create dynamic and responsive page structures.

9. **Content Priority:** Prioritize and display essential content first for smaller screens, then enhance the layout for larger screens.

10. **Performance Optimization:** Optimize images and minimize the use of large files to ensure faster loading times, especially on mobile devices.
