How CSS Specificity Works

When two rules target the same element, specificity decides the winner — not source order alone. Understanding this saves hours of debugging.

Why CSS specificity Matters

Specificity wars cause !important sprawl and unmaintainable stylesheets — understanding the cascade prevents months of CSS debt.

Inline > ID > class > element. When styles conflict, count selectors — don't escalate with !important unless documenting why.

  • Inline styles beat classes
  • ID beats class
  • Class beats element
  • !important overrides (avoid)
  • Use devtools Computed tab
