Testimonials Grid Section Main

I'm looking for feedback on my 'Testimonials Grid Section Main' project, and I'm particularly interested in your insights in the following areas:

1. Layout and Responsiveness: I want to ensure that the layout of the testimonials grid is visually appealing and that it works well on various screen sizes and devices. In particular, I've noticed that in the mobile version, it may be necessary to increase the viewport height to fully view the design, and I'd appreciate feedback on this aspect.

2. CSS Styling: I'd appreciate feedback on my CSS techniques, including the styling of elements and any opportunities for improvement in terms of design and aesthetics.

3. Code Organization and Structure: I'm keen to know if the code is well-organized, efficient, and follows best practices. Please provide insights on the logical structure of my code.

4. Accessibility and User Experience: Any suggestions related to improving the accessibility and overall user experience of the project are highly valued.

-- Any Specific Enhancements: If there are specific aspects or features you believe could be enhanced or refined, please share your thoughts.

Your feedback will greatly assist me in refining this project, and I'm eager to learn from your valuable insights. Thank you in advance for your help!
