What is CSS selectors specificity?

Can you explain what CSS selectors specificity is?

Sure! CSS selectors specificity determines which styles are applied to an element when multiple rules could apply. It's calculated based on the types of selectors used.

How is specificity calculated?

Specificity is calculated using a four-part value: inline styles (1,0,0,0), IDs (0,1,0,0), classes/attributes/pseudo-classes (0,0,1,0), and elements/pseudo-elements (0,0,0,1). The higher the value, the more specific the selector.

Can you give me an example of how specificity works?

Absolutely! If you have a rule like #header { color: red; } and another like .highlight { color: blue; }, the #header rule will take precedence because IDs have higher specificity than classes.

What happens if two selectors have the same specificity?

If two selectors have the same specificity, the one that appears later in the CSS file will take precedence.
