Dark Mode

ELI5 — The Vibe Check

The feature every user demands and every developer underestimates. 'Just make the background dark' they said. It'll be easy, they said. Then you discover that dark mode means rethinking every color, shadow, border, image, and icon in your entire app. Oh, and users want it to follow their system preference AND have a manual toggle.

Real Talk

Dark mode is a UI color scheme using light text on dark backgrounds. Implementation involves CSS custom properties for theming, prefers-color-scheme media query for system preference detection, and a toggle mechanism with persistence. Challenges include image contrast, shadow visibility, and ensuring sufficient color contrast ratios for accessibility.

/* CSS dark mode with system preference */
:root {
  --bg: #ffffff;
  --text: #1a1a1a;
}

@media (prefers-color-scheme: dark) {
  :root {
    --bg: #0a0a0a;
    --text: #e5e5e5;
  }
}

body {
  background: var(--bg);
  color: var(--text);
}
