[UI Enhancement] Improve "Download the App Now" Section & Customize Scrollbar

Description

I would like to enhance the "Download the App Now" section by improving:

• Background design
• Text alignment
• Overall UI to make it more visually appealing and user-friendly

Additionally, I propose making the scrollbar more visually cohesive with the theme of the website by:

• Adding colors that complement the existing UI
• Customizing the scrollbar with subtle borders and styling to enhance aesthetics

Benefits

• A more polished and modern UI
• A visually appealing scrollbar that aligns with the overall theme
• Improved user experience

Proposal

I will handle the entire UI improvement and ensure it integrates well with the website’s design. Since these are mostly CSS-related changes, I can complete them quickly and efficiently.

Additional Context

I am a participant of Social Winter of Code 2025 (SWOC '25) and would love to contribute to this project. Kindly assign this issue to me, and I’ll complete it in no time! 🚀

Looking forward to working on this! 😊
