CSS Styling Standards

Use CSS Variables for ALL Colors

NEVER hardcode colors in component styles. Always use CSS variables defined in src/assets/style.css.

Available variables:

--primary       /* Primary brand color */
--primary-dark  /* Darker primary for hover states */
--secondary     /* Secondary/muted color */
--success       /* Success states (green) */
--warning       /* Warning states (orange) */
--danger        /* Error/danger states (red) */
--bg            /* Page background */
--bg-card       /* Card/panel background */
--text          /* Primary text color */
--text-light    /* Secondary/muted text */
--border        /* Border color */
--link          /* Link color (bright blue in dark mode) */

Bad:

.my-card {
  background: white;
  color: #1a1a1a;
}

Good:

.my-card {
  background: var(--bg-card);
  color: var(--text);
}

Detail Pages - Use Global Styles

All detail pages (MachineDetail, PCDetail, PrinterDetail, ApplicationDetail) should use the unified global styles from style.css:

• .detail-page - Container wrapper
• .hero-card - Main hero section with image and info
• .hero-image, .hero-content, .hero-title, .hero-meta, .hero-details
• .section-card - Info sections
• .section-title - Section headers
• .info-list, .info-row, .info-label, .info-value
• .content-grid, .content-column - Two-column layout
• .audit-footer - Created/modified timestamps

Only add scoped styles for page-specific elements (e.g., supplies grid for printers, version list for applications).

PrinterDetail.vue is the Master Template for Detail Pages

Use PrinterDetail.vue as the reference for new detail pages. Follow its structure and styling patterns.

List Pages - Use Global Styles

All list pages should use the unified global styles from style.css:

• .page-header - Header with title and action button
• .filters - Search and filter controls
• .card - Main content container
• .table-container - Scrollable table wrapper
• table, th, td - Table styling
• .pagination - Page navigation
• .badge, .badge-success, etc. - Status badges
• .actions - Action button column

PrintersList.vue is the Master Template for List Pages

Use PrintersList.vue as the reference for new list pages. It has NO scoped styles - everything uses global CSS.

Only add scoped styles for page-specific elements (e.g., icon cells for applications, stats badge for knowledge base).

Dark Mode Support

Dark mode is automatic via @media (prefers-color-scheme: dark). Using CSS variables ensures colors adapt automatically - no extra work needed per page.

Component Organization

• Global styles: src/assets/style.css
• Page-specific styles: Scoped <style scoped> block, only for unique elements
• Font sizes: Use rem units, base is 18px for readability on 1080p
