- Image scaling: Ensure images are appropriately sized for different devices.

Ideal skills and experience:
- Proficiency in responsive web design
- Strong understanding of navigation menu implementation
- Expertise in typography and readability adjustments
- Experience with image optimization for mobile layouts

Please provide examples of previous work and a brief proposal.
