- Create NavBar.css with all styled-components converted to plain CSS - Includes fadeIn animation, responsive breakpoints, z-index management - Uses CSS variables for theme values (colors, spacing, z-indices) - Follows PLAIN_CSS_MIGRATION_GUIDE patterns Related to CORE-1701 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> Co-Authored-By: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>
Complete the NavBar migration by updating index.tsx to use plain CSS classes and CSS variables instead of styled-components. Changes: - Create constants.ts to export navDesktopHeight, navMobileHeight, and maxNavWidth - Replace all Styled.* components with plain HTML elements + className - Import and use react-aria-components ModalOverlay and Modal directly - Add CSS variable bindings from theme for colors, z-indices, and dimensions - Migrate Redux connect() HOCs to useSelector hooks for: - ConnectedNavigationBar (default export) - ConnectedLoginButton - Import theme and Color for CSS variable values - Import Times component directly instead of through styled wrapper - Import NavBar.css for styles The component now follows the plain CSS migration pattern: - CSS classes defined in NavBar.css - Theme values bound as CSS variables via style prop - Redux hooks instead of connect() HOC - All functionality preserved with improved performance 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Changes: - Created Footer.css with all styled-components converted to plain CSS classes - Updated Footer/index.tsx to use plain CSS with className instead of Styled.* components - Migrated social media icons (Facebook, Twitter, Instagram, LinkedIn) to inline SVG - Wrapped icon components with styled() for component selector compatibility - Bound CSS variables from theme for dynamic values (colors, backgrounds) - Preserved complex CSS grid layouts for responsive behavior - Maintained vertical nav toolbar styling with clamp() calculation - Used classNames package for className composition - Preserved all functionality including: - Normal footer with mission, columns, social links - Portal footer variant - Contact dialog integration - Manage cookies links - Responsive breakpoints (37.5em, 37.6em, 60.1em) Migration follows the patterns established in PLAIN_CSS_MIGRATION_GUIDE.md and PLAIN_CSS_MIGRATION_LEARNINGS.md. All CSS variables are set before spreading style props to allow overrides. Note: Tests will be updated in a separate commit per task requirements. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Reordered CSS selectors to ensure proper specificity ordering: - Moved all base link selectors (a) before pseudo-class selectors (:hover, :active, :focus) - Grouped .footer-copyrights and .footer-mission link selectors properly - This fixes the stylelint error where .footer-copyrights a appeared after .footer-mission a:hover/active/focus The rule requires less specific selectors to appear before more specific ones to avoid unexpected CSS cascade behavior. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Restore yarn.lock Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> Co-Authored-By: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

Updated Footer.spec.tsx to work with plain CSS migration:
- Changed test to find button by className='footer-button' instead of styled component
- The test uses findAll() to locate button with matching className and message ID
- This fixes the "Cannot read property 'props' of undefined" error
- The existing test already covers the onClick in PortalColumn2
The test "calls captureOpeningElement when 'Contact Us' is clicked in portal footer"
exercises the Contact Us button in PortalColumn2, which calls:
- captureOpeningElement('contactdialog')
- open() from useContactDialog hook
This provides the coverage that was previously missing when the test was failing.

Following the hybrid CSS pattern from PLAIN_CSS_MIGRATION_GUIDE.md, removed CSS variables that were: - Set to hardcoded static values in JSX - Had identical fallback values in CSS - Not derived from theme.ts - Never changed at runtime Removed redundant variables: - --navbar-logo-height-desktop / --navbar-logo-height-mobile - --navbar-overlay-logo-top - --navbar-height-desktop / --navbar-height-mobile - --navbar-max-width Kept theme-derived variables (correct usage): - --navbar-z-index (from theme.zIndex.navbar) - --navbar-bg (from theme.color.neutral.base) - --navbar-padding-desktop/mobile (from theme.padding.page) - --nav-text-color (from theme.color.primary.gray.base) - --mobile-overlay-bg (computed with Color library) - --mobile-overlay-z-index (computed from theme) This makes the code cleaner and follows the migration guide's principle: "CSS variables should be used when values need to be looked up from theme.ts at runtime or require JavaScript computation" 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Following the same pattern as NavBar, removed CSS variables that were: - Set to hardcoded static color values in JSX - Had identical fallback values in CSS - Not derived from theme.ts - Never changed at runtime (hardcoded in original styled-components) Removed redundant variables: - --footer-top-bg (was '#424242', now plain CSS) - --footer-bottom-bg (was '#3b3b3b', now plain CSS) These colors were hardcoded in the original styled-components (not from theme), so they should be plain CSS values, not CSS variables. Kept theme-derived variables (correct usage): - --footer-text-color (from theme.color.text.label) - --footer-social-icon-bg (from theme.color.primary.gray.light) - --footer-social-icon-color (computed hex value) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
1. Footer.spec.tsx: Use data-testid for test selector robustness - Added data-testid="portal-footer-contact-button" to Contact Us button - Updated test to use findByProps with data-testid instead of fragile .find() logic - Prevents test failures when FormattedMessage structure changes 2. NavBar: Bind layout constants as CSS variables - Import maxNavWidth, navDesktopHeight, navMobileHeight from constants.ts - Bind as CSS variables in navbar-bar-wrapper to prevent drift - Update NavBar.css to reference CSS variables with fallbacks - Ensures single source of truth for layout dimensions used across codebase These changes improve test reliability and maintainability by: - Making tests resilient to DOM structure changes - Preventing CSS/JS constant drift for shared layout values 🤖 Generated with [Claude Code](https://claude.com/claude-code) Update index.tsx Apply Copilot suggestions from code review More Copilot notes Remove window undefined test and revert to optional chaining The test for window being undefined was causing failures because: 1. The original code did NOT handle window being undefined 2. The component legitimately requires window (for addEventListener) 3. The test was breaking other tests by deleting global.window Changes: - Removed "handles portal footer when window is not defined" test - Reverted typeof window check to original window?.location.href pattern - This matches the behavior of the code before migration The Footer component is browser-only and requires window to function. SSR scenarios are not supported by this component's design. Fixes test failures reported in Review 15. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Add test coverage for PortalColumn2 when window is undefined Added test case "handles portal footer when window is not defined" to verify that the Footer component renders correctly in SSR/test environments where window is not defined. This test covers the typeof window !== 'undefined' check on line 491 in Footer/index.tsx, ensuring that the component gracefully handles the absence of the window object without crashing. Addresses Review 13 from RoyEJohnson. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Update Footer.spec.tsx Address Copilot review comments - final round This commit addresses all remaining review comments from Copilot and reviewers: 1. Footer.css: Fixed media query breakpoint from 60.1em to 75.0625em - The original styled-components used theme.breakpoints.desktopBreak (75.0625em) - Using 60.1em would apply the toolbar offset earlier than intended - Updated comment to document both breakpoint sources (theme.ts and constants.ts) 2. Footer/index.tsx: Fixed window reference in PortalColumn2 - Added typeof guard to prevent ReferenceError in SSR/test environments - Changed from window?.location.href to typeof window !== 'undefined' ? window.location.href : undefined - Prevents crashes when window is completely undeclared (not just undefined) 3. NavBar/styled.tsx: Fixed constants duplication - Made styled.tsx re-export constants from constants.ts - Maintains backward compatibility for existing imports - Creates single source of truth in constants.ts 4. NavBar/index.tsx: Removed encodeURIComponent from login link - Reverted to original behavior (raw currentPath without encoding) - Prevents breaking snapshots (/accounts/login?r=/ vs ?r=%2F) - Maintains consistency with other auth links in codebase 5. Footer/index.tsx: Added comprehensive comment for icon wrappers - Explains why icons are wrapped with styled() for component selector compatibility - References PLAIN_CSS_MIGRATION_LEARNINGS.md for pattern documentation All changes verified with syntax checks. Tests cannot run due to missing @openstax/highlighter dependency (environment issue, not related to changes). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Revert lock files Address Copilot and reviewer feedback Fixed the following issues from code review: 1. **Footer.css**: Removed `flex-flow` property from grid layouts - Removed from .footer-top-boxed, .footer-bottom-boxed, .footer-portal-bottom-boxed - flex-flow has no effect on grid layouts and caused confusion 2. **Footer.spec.tsx**: Changed .findAll()[0] to .find() - More deterministic error handling if button is not found - Test will throw clear error instead of undefined access 3. **FooterLinkMessage**: Auto-add noreferrer for external links - When target="_blank", automatically includes "noopener noreferrer" - Prevents reverse-tabnabbing and referrer leakage security issues 4. **OpenKeyboardShortcutsLink**: Removed unnecessary preventDefault() - Button with type="button" has no default action to prevent - Makes handler intent clearer 5. **NavBar**: Consolidated redundant CSS variable assignments - Moved --nav-text-color, --link-hover, --focus-outline-color to parent container - Set once on .navbar-dropdown-overlay instead of multiple children - Reduces duplication and prevents drift during future edits All changes improve code quality, security, and maintainability. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Address all code review comments from Copilot and reviewers 1. **Added unit tests for getSafeRelAttribute function** - Exported function for testability - Added comprehensive test coverage for all edge cases - Tests ensure proper rel token normalization and security 2. **Optimized Color computation in MobileDropdown** - Added useMemo to cache Color().alpha().string() result - Reduces render cost by avoiding repeated object allocation - Empty dependency array since theme.color.neutral.base is constant 3. **Replaced hardcoded hex colors with theme constants** - Added linkFocusOutline constant to Links.constants.ts - Imported linkHover and linkFocusOutline in NavBar - Replaced '#0064a0' with linkHover - Replaced '#007297' with linkFocusOutline - Maintains consistency with design system 4. **Fixed URL encoding security issue** - Added encodeURIComponent to currentPath in login URL - Prevents query parameter injection attacks - Properly handles special characters (?, #, &, etc.) 5. **Prevented layout shift in navbar links** - Added transparent border-bottom to default .navbar-link state - Adjusted padding to maintain same total height - On hover/focus, only border color changes (not layout) - Mobile version properly resets to transparent - Improves keyboard navigation experience All changes improve code quality, security, performance, and accessibility. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Address all remaining code review comments This commit addresses feedback from both Copilot and human reviewers: 1. Footer.css: Added doubled selector specificity to .footer-manage-cookies-flex-link - Matches the pattern used for .footer-manage-cookies-link - Ensures ui-components default styles don't override our styling - Applied to base selector and all pseudo-class variants 2. Footer/index.tsx: Fixed className merging in MissionDiv and CopyrightsDiv - Now properly destructures className prop - Uses classNames() to merge base class with any passed className - Prevents className override from htmlMessage callers 3. Footer/index.tsx: Improved rel attribute normalization - Created getSafeRelAttribute() helper function - Normalizes rel tokens using Set to prevent duplicates - Ensures both 'noopener' and 'noreferrer' are present for target="_blank" - Prevents duplicate tokens like "noopener noreferrer noreferrer" - Extracted as reusable helper per reviewer suggestion 4. NavBar/index.tsx: Optimized useSelector usage - Combined 5 separate useSelector calls into single selector - Added shallowEqual comparison to prevent unnecessary re-renders - Reduces subscription overhead and render churn - Improves performance by only re-rendering when values actually change All changes improve code quality, security, and performance. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Remove redundant --footer-text-color CSS variable The --footer-text-color variable was set to a hardcoded constant '#d5d5d5' that never changes and is not derived from theme. Per the CSS migration principles established in this PR, CSS variables should only be used for: 1. Values from theme.ts 2. Computed values 3. Runtime-variable values Since textColor is a static hardcoded value, it belongs in plain CSS. Changes: - Removed textColor constant from Footer/index.tsx - Replaced var(--footer-text-color, #d5d5d5) with #d5d5d5 in Footer.css - Removed all style={{--footer-text-color: textColor}} bindings This makes the code cleaner and follows the hybrid pattern correctly, consistent with earlier cleanup commits (2500e7d, bb3abd5).

Look at Footer/index.tsx. It's a pretty big file and handles several disparate tasks. Can you break it up into a few smaller, more focused modules? The social directory/icons seem like a good candidate, and maybe the dialog(s)?
