25-25: Improve accessibility for decorative icon.The alt text "Online Icon" doesn't convey meaningful information beyond decoration. For purely decorative images, use an empty alt attribute or add
aria-hidden="true".Apply this diff:
- <img alt="Online Icon" src={onlineIcon} className="onlineIcon" /> + <img alt="" src={onlineIcon} className="onlineIcon" aria-hidden="true" />

1-107: LGTM! Clean and modern styling.The CSS refactor introduces a well-structured, accessible, and responsive design. The implementation includes:
- Clear separation of concerns with dedicated classes (.intro, .usersSection, .activeContainer, .activeItem)
- Cross-browser scrollbar styling (standard + WebKit)
- Smooth hover effects and transitions
- Appropriate responsive adjustments for small screens
The max-height constraints on .activeContainer (220px/180px) effectively create a scrollable user list, which is a good UX decision when many users are present.

Critical: Type mismatch between users initialization and usage.
In client/src/components/Chat/Chat.js (line 18), users is initialized as an empty string (useState('')), but this component treats it as an array. If users is set to a non-empty string, the conditional check users.length > 0 will pass, but users.map will throw a runtime error since strings don't have the expected .map behavior for object destructuring.
Apply this verification script to confirm how users is set throughout the codebase:
#!/bin/bash
# Description: Verify how users state is initialized and updated in Chat.js
# Find where users state is set
rg -A 3 'setUsers' client/src/components/Chat/Chat.js
# Check if users is expected to be an array elsewhere
ast-grep --pattern 'users.map'🤖 Prompt for AI Agents
In client/src/components/TextContainer/TextContainer.js around lines 19 to 31,
the component assumes users is an array but upstream code may initialize it as a
string, causing users.map to throw; ensure users is always an array by changing
the Chat.js users state default to an empty array (useState([])) and/or add a
runtime guard in this file to only map when Array.isArray(users) and
users.length > 0 (or coerce non-array to an empty array) so mapping never runs
on a string or other non-iterable value.

Consider using a more unique key.
Using name as the React key assumes all usernames are unique. If duplicate names exist, React may have reconciliation issues. Consider using a unique identifier like userId or falling back to an index if unavailable.
Example approach:
- <div key={name} className="activeItem">
+ <div key={`${name}-${index}`} className="activeItem">Note: This requires updating the map callback to include the index parameter.
Committable suggestion skipped: line range outside the PR's diff.
🤖 Prompt for AI Agents
In client/src/components/TextContainer/TextContainer.js around line 24, the JSX
uses key={name} which can collide when usernames repeat; change the map callback
to accept the index and use a truly unique key (preferably the user's unique id
property like userId) and if that id is not available fall back to a stable
composite key such as combining name with the index; update the map signature to
include the index and replace key usage accordingly to avoid reconciliation
issues.
