Make Mail Karo Assistant Fully Responsive Across Screen Sizes

📌 Problem
The **Mail Karo Assistant** widget does not scale or adapt properly on different screen sizes.

Current issues observed:
- Assistant UI looks broken when screen is maximized
- Poor responsiveness on smaller screens (laptop / mobile)
- Content feels cramped or misaligned
- Overall UX feels unpolished and hard to use

This makes the assistant look unfinished and reduces usability, especially on non-standard screen sizes.

✅ Goal
Make the **Mail Karo Assistant fully responsive, flexible, and visually consistent** across all screen sizes.

The assistant should:
- Adapt smoothly to screen resizing
- Work well on desktop, laptop, tablet, and mobile
- Maintain proper spacing, alignment, and readability
- Feel like a polished SaaS chat assistant

📂 File Location
1. Assistant UI structure → `index.html` -> between the footer section and back to top button
2. Styling & responsiveness → `Homepage CSS` -> chatbot.css
3. Interaction logic (if needed) → `Homepage JS` -> chatbot.js

---

💡 Expected Improvements
- Responsive width and height (avoid fixed sizes)
- Proper padding and spacing for buttons and messages
- Scroll behavior should work smoothly
- Assistant should not overflow or break layout
- Close / minimize button should remain accessible on all screens

*(Exact UI implementation is flexible, but responsiveness is mandatory.)*

✅ Acceptance Criteria

- Assistant works properly on **laptop and tablet**
- Assistant is usable on **mobile screens**
- No UI breakage on screen resize
- No horizontal overflow or clipped content

🛠️ Suggested Implementation

✅ Preferred:
- Use flexible units (`%`, `vh`, `vw`, `rem`)
- CSS media queries
- Flexbox / Grid for layout
- Max-width + auto scaling

✅ Avoid:
- Fixed pixel widths/heights that break responsiveness

---

🎯 Why this matters
The assistant is a **key user interaction point**.

Improving responsiveness will:
- Improve user trust
