How can I manage selector specificity to avoid conflicts in a large stylesheet?

Example Concept: CSS specificity is determined by the types of selectors used: inline styles, IDs, classes, attributes, and element selectors. Specificity is calculated as a score, where inline styles have the highest priority, followed by IDs, then classes and attributes, and finally element selectors. To manage specificity, use classes over IDs, avoid inline styles, and utilize CSS methodologies like BEM (Block Element Modifier) to maintain a clear hierarchy.
