Example Concept: CSS specificity determines which styles are applied when multiple rules could apply to the same element. Specificity is calculated based on the types of selectors used: inline styles have the highest specificity, followed by IDs, classes/attributes/pseudo-classes, and finally, element selectors. To manage specificity, use a consistent naming convention, avoid using IDs for styling, and leverage CSS methodologies like BEM (Block Element Modifier) to keep specificity low and predictable.
