Improve UI/UX of firstcontributions.github.io

📌 Summary
The current UI of the [firstcontributions.github.io](https://firstcontributions.github.io/) site appears quite basic and lacks visual styling in several areas. As a first-time contributor, I'd love to enhance the user interface to make it more modern, visually appealing, and beginner-friendly without affecting existing functionality.

🎯 Areas for Improvement
🧭 Navigation

Add consistent header/footer

Improve spacing and layout for better readability

🎨 Styling

Introduce a modern color palette and better typography

Use CSS or utility-first framework (like TailwindCSS, if acceptable)

Add visual hierarchy for section titles and content

📱 Responsiveness

Make the layout mobile-friendly

Fix padding/margin issues on smaller screens

💻 Component Polish

Style buttons, links, and cards with hover/focus states

Use semantic HTML where appropriate

✅ Benefits
Improves first impressions for newcomers to open source

Makes the content easier to read and interact with

Gives contributors a more polished and welcoming interface

🛠️ Tech Stack Suggestion
Happy to implement using plain CSS or, if allowed, introduce lightweight frameworks like TailwindCSS to keep the site minimal and maintainable.

🙋‍♂️ Proposal
If approved, I’d like to:

Create mockups or quick layout suggestions

Start with a small PR to revamp the homepage section-by-section

Keep changes modular and accessible
