Getting Specific About CSS Specificity

CSS styling prioritization depends on specificity, a system determining which style rule takes precedence when conflicts arise. Specificity is calculated using a four-number notation representing inline styles, IDs, classes, and elements. Each identifier contributes points, with higher specificity winning the style conflict. The notation uses commas to separate the values, preventing simple numerical addition for comparison. This system handles situations with numerous classes, avoiding ambiguity in interpretation. The `:is()` and `:where()` selectors offer improved compound selector syntax for styling multiple elements. `:is()` specificity is determined by the most specific element within the list. `:where()` always has a specificity of zero, regardless of its contents, allowing for specificity manipulation. This feature provides flexibility in controlling style application. Understanding CSS specificity enhances code predictability and style control.
