A guide to CSS Specificity Rules

[balajiseo]

Understanding CSS specificity is crucial for effective styling. It determines which CSS rules apply when conflicts arise. Specificity is calculated based on selector types: inline styles, IDs, classes/attributes/pseudo-classes, and elements/pseudo-elements. Inline styles have the highest priority, followed by IDs, then classes, and lastly, elements. A more specific selector overrides less specific ones. Calculate specificity by counting each selector type. Universal selectors and combinators don't affect it.
