Updated TextContainer styles for better UX and responsive design #166
Conversation
WalkthroughCSS refactors the TextContainer styles, introducing new layout, sections, item styling, and responsive rules. JS updates markup and structure to match new classes, adds a conditional render for the users list, and separates icon and username elements. No exports or public API changes. Changes

1-107: Optional: Consider CSS variables for better maintainability.While the current implementation works well, using CSS variables for the color palette would improve maintainability and enable easier theming in the future.
Consider adding CSS variables at the top of the file or in a global stylesheet:
:root { --color-text-primary: #111; --color-text-secondary: #555; --color-text-tertiary: #222; --color-text-base: #333; --color-bg-primary: #fafafa; --color-bg-secondary: #ffffff; --color-border: #e2e2e2; --color-hover-bg: #e6f7ff; --color-scrollbar: #ccc; }Then replace hard-coded values throughout:
.textContainer { color: var(--color-text-base); background-color: var(--color-bg-primary); } .intro h1 { color: var(--color-text-primary); } /* etc. */client/src/components/TextContainer/TextContainer.js (1)
23-28: Useidas the React key
Destructure and use the uniqueidinstead ofnameto avoid key collisions:- {users.map(({ name }) => ( - <div key={name} className="activeItem"> + {users.map(({ name, id }) => ( + <div key={id} className="activeItem"> <img alt="Online Icon" src={onlineIcon} className="onlineIcon" /> <span className="username">{name}</span> </div>

7-17: LGTM! Proper accessibility attributes for emoji.The intro section is well-structured with appropriate accessibility attributes (
role="img"andaria-label) for the emoji spans, ensuring screen readers can convey their meaning.client/src/components/TextContainer/TextContainer.css (5)
1-19: LGTM! Modern styling with good visual hierarchy.The updated
.textContainerstyles successfully introduce modern shadows, proper spacing, and a clean color scheme that enhances readability and UX.
42-64: Excellent scrollbar customization for improved UX.The
.activeContainerstyles successfully implement improved scroll behavior with:
- Smooth scrolling with
overflow-y: auto- Custom thin scrollbar for Firefox (
scrollbar-width: thin)- WebKit-specific styling for Chrome/Safari
- Reasonable
max-height: 220pxto prevent excessive vertical growth
66-80: Nice interactive hover effects!The
.activeItemstyling provides smooth, modern hover feedback with:
- Subtle background color change
- Gentle scale animation (
scale(1.02))- Appropriate transition timings (0.2s for color, 0.1s for transform)
The
cursor: defaultis appropriate for non-interactive items.
94-107: Well-implemented mobile responsiveness.The responsive design adjustments for screens ≤480px are appropriate:
- Reduced heading size prevents overflow
- Flexible container widths adapt to smaller screens
- Adjusted scroll height maintains usability on mobile
21-33: Clean typography hierarchy. The.introsection styling establishes a clear visual hierarchy with appropriate font sizes and colors—contrast ratios for #111111 and #555555 on #fafafa pass WCAG AAA.

🧩 Analysis chain
Verify users type or add explicit array check.
The conditional check users && users.length > 0 assumes users is an array, but the relevant code snippet from Chat.js (line 18) shows it's initialized as an empty string: const [users, setUsers] = useState('');. While an empty string is falsy and won't cause immediate issues, if users is set to a non-empty non-array value, users.map() on line 23 will throw a runtime error.
Consider using a more defensive check:
- {users && users.length > 0 && (
+ {Array.isArray(users) && users.length > 0 && (
<div className="usersSection">Alternatively, ensure the parent component (Chat.js) initializes users as an empty array instead of an empty string:
// In Chat.js
const [users, setUsers] = useState([]);Run this script to verify how users is managed throughout the codebase:

#!/bin/bash

Initialize users as an array and guard against non-arrays
