HTML and CSS

While building the project, I found the following challenges:

1. Cross-Browser Compatibility: Ensuring consistent behavior and appearance across different browsers can be tricky, especially when dealing with complex CSS features.

2. Accessibility: Making the page accessible to all users required careful consideration of ARIA attributes and testing with screen readers.

3. Responsive Design Edge Cases: Handling extreme screen sizes and orientation changes presented some difficulties in ensuring a seamless user experience.

4. Optimizing Images: Balancing image quality and page load speed while supporting various device resolutions required careful optimization.

Areas of uncertainty in my code include:

1. Performance Optimization: I'm unsure if I've implemented the most efficient techniques to optimize page loading and rendering speed.

2. Browser Compatibility: There may be compatibility issues with older browsers that I haven't thoroughly tested.

3. Accessibility: While I've made efforts to improve accessibility, I'm uncertain if I've covered all aspects comprehensively.

4. Code Refactoring: I may have opportunities to refactor my code for better organization and maintainability.

I plan to address these uncertainties through thorough testing, code review, and further research as needed to improve the project.
