User list hover effect (activeItem:hover) — improves interactivity. #165
Conversation
WalkthroughUpdated the TextContainer component’s markup and associated CSS. Introduced new structural wrappers and class names, refined conditional rendering to require a non-empty users array, and overhauled styles for layout, user list presentation, and typography, including scrollable user cards and removed legacy media query behavior.

24-28: Width cap: consider a slightly larger max-width for long names. 300px may truncate multi-word names; 360–420px often reads better on desktop.-.usersSection { +.usersSection { margin-top: 2rem; width: 100%; - max-width: 300px; + max-width: 360px; /* consider 360–420px */ }
30-40: Scrollable list: add momentum scrolling and safe overscroll. Improves touch UX and avoids scroll chaining..activeContainer { display: flex; flex-direction: column; gap: 0.5rem; max-height: 200px; /* scroll if many users */ overflow-y: auto; padding: 0.5rem; border: 1px solid #ddd; border-radius: 0.5rem; background-color: #f9f9f9; + -webkit-overflow-scrolling: touch; + overscroll-behavior: contain; }
56-63: Icon/label sizing is fine; consider aligning baselines. If you see vertical misalignment, adddisplay: inline-blockandvertical-align: middle..onlineIcon { - width: 18px; - height: 18px; + width: 18px; + height: 18px; + display: inline-block; + vertical-align: middle; } .username { font-weight: 500; }client/src/components/TextContainer/TextContainer.js (4)
23-27: Use semantic list or add roles; improve icon alt. For assistive tech, prefer<ul>/<li>or at minimumrole="list"/role="listitem". The icon’s alt text should be either empty if decorative, or simply “Online.”- <div className="activeContainer"> - {users.map(({ name }) => ( - <div key={name} className="activeItem"> - <img alt="Online Icon" src={onlineIcon} className="onlineIcon" /> - <span className="username">{name}</span> - </div> - ))} - </div> + <ul className="activeContainer" role="list"> + {users.map(({ name }) => ( + <li key={name} className="activeItem"> + <img alt="Online" aria-hidden="false" src={onlineIcon} className="onlineIcon" /> + <span className="username">{name}</span> + </li> + ))} + </ul>If the icon is purely decorative, use
alt="" aria-hidden="true"instead.
24-24: Key stability.key={name}will collide if names repeat; prefer a stable unique id if available, or a composite fallback.- {users.map(({ name }) => ( - <div key={name} className="activeItem"> + {users.map(({ id, name }, idx) => ( + <div key={id ?? `${name}-${idx}`} className="activeItem">
23-27: Keyboard focusability. If items are non-interactive, don’t addtabIndex. If they’re intended to be clickable in the future, switch to buttons/links or addtabIndex={0}with proper key handlers. Mirror hover styles via:focus-visiblein CSS (see CSS comment).
35-35: Consider PropTypes (or TS) forusers. Helps catch the array-vs-string issue early.import './TextContainer.css'; const TextContainer = ({ users }) => ( @@ export default TextContainer; +// TextContainer.propTypes = { +// users: PropTypes.arrayOf(PropTypes.shape({ name: PropTypes.string.isRequired })), +// };

🛠️ Refactor suggestion | 🟠 Major
Hover added—also mirror it for keyboard users. Provide a visible focus style; current items are not focusable or styled on focus.

+.activeItem:focus-visible {

In client/src/components/TextContainer/TextContainer.css around lines 42 to 54,
the hover state was added but there is no visible focus style or keyboard
accessibility; add a :focus and :focus-visible rule matching the hover
background (and optionally an outline for clarity) so keyboard users see the
same feedback, and then in the component ensure each item is keyboard-focusable
by using semantic focusable elements (e.g., convert to <li> inside a <ul>/<ol>
or assign tabIndex={0} only if the item is meant to be interactive/navigable) so
the focus styles are actually reachable via keyboard.

Guard can allow non-arrays through; tighten to avoid runtime .map errors. Strings have length > 0, so users && users.length > 0 could pass and then users.map would throw. The repo snippet shows const [users, setUsers] = useState('') (client/src/components/Chat/Chat.js Line 18), which increases this risk.
- {users && users.length > 0 && (
+ {Array.isArray(users) && users.length > 0 && (
<div className="usersSection">
<h1>People currently chatting:</h1>
<div className="activeContainer">
- {users.map(({ name }) => (
- <div key={name} className="activeItem">
+ {users.map(({ name }) => (
+ <div key={name} className="activeItem" role="listitem">
<img alt="Online Icon" src={onlineIcon} className="onlineIcon" />
<span className="username">{name}</span>
</div>
))}
</div>
</div>
)}Additionally, consider initializing users to an empty array in Chat.js to match the intended type (see separate comment).

client/src/components/TextContainer/TextContainer.js around lines 19 to 31: the
current guard users && users.length > 0 allows non-array values (e.g. strings)
to pass and cause users.map to throw; update the condition to ensure users is an
array (e.g. Array.isArray(users) && users.length > 0) before mapping, and also
update client/src/components/Chat/Chat.js to initialize users state to an empty
array (useState([])) so the prop type matches expected usage.
