Layout Expansion

The chat window should be full-height and resizable, taking most of the viewport (like ChatGPT).

Use a flexbox or grid layout so the chat section grows dynamically with the screen size.

Example:

.chat-container {
display: flex;
flex-direction: column;
height: 100vh; /* full vertical space */
width: 100%; /* or 70% if sidebar exists */
border-left: 1px solid #ddd;
}


Message Bubbles Style

Each user message should be in a right-aligned bubble, AI responses in left-aligned bubbles.

Use soft background colors (like #f1f1f1 for AI, #d1e7ff for user).

Add padding, rounded corners, and spacing for readability.

Scrollable History

The chat history panel should be scrollable vertically, with new messages auto-scrolling into view.

Example:

.chat-history {
flex-grow: 1;
overflow-y: auto;
padding: 1rem;
}


Input Box Design

Place the input bar fixed at the bottom, like ChatGPT.

Allow multiline typing with textarea that auto-expands.

Example:

.chat-input {
display: flex;
padding: 0.5rem;
border-top: 1px solid #ddd;
background: #fff;
}

.chat-input textarea {
flex-grow: 1;
resize: none;
border: none;
outline: none;
padding: 0.75rem;
border-radius: 8px;
}


Responsive Behavior

On large screens → Sidebar + Chat side by side (like now).

On small screens → Sidebar collapses, chat takes full width.

Optional Enhancements

Add typing indicator (e.g., “FloatChat is typing…”).

Show time stamps under each message.

Add buttons/suggestions as quick-reply chips (like Gemini).
