9. Another real-world angle

10. Best practices checklist

  • Prefer classes over ids for reusable StyleVerse components.
  • Use design tokens (CSS variables) for color and spacing.
  • Mobile-first media queries; test keyboard focus.
  • Keep specificity low — avoid !important except rare overrides.
  • Animate transform/opacity when you can; respect prefers-reduced-motion.

11. Common mistakes

  • Playful colors on balance card — banking needs trust tones.
  • Transaction text too light failing contrast audit.

12. Practice in the browser

  1. Link BankingDashboard.css to dashboard HTML shell.
  2. Add balance, three actions, and five txn rows.
  3. Test tabular-nums alignment on varying amounts.
  4. Shrink to 320px — actions should wrap with flex-wrap.

Experiments

  • Add .sv-bank-txn__credit { color: #2e7d32; } for deposits.
  • Set .sv-bank-shell sidebar column at 768px breakpoint.

13. FAQ

Where should I put CSS for Banking Dashboard?

Start in a <style> block or styles.css linked from HTML. Later use CSS Modules, Tailwind, or tokens in a design system.

Why is my rule not applying?

Check selector match, typos, specificity, and whether a more specific rule or inline style wins. DevTools Computed tells the truth.

Flexbox or Grid for this?

Flex for one direction (toolbars, card rows). Grid for two-dimensional page frames. Many UIs use both.
