  Remember, use classes to create reusable styles and reduce specificity.

  Specificity in CSS refers to how the browser decides which CSS rule to apply to an element when there are multiple rules that could apply. Specificity is based on the combination of selectors used in the CSS rules.

  In general, specificity is calculated by adding up the values assigned to each type of selector in the CSS rule. For example, an ID selector has a higher specificity than a class selector, and a tag selector has a lower specificity than any other type of selector.

  Here are some examples of how specificity is calculated in CSS:

  • p has a specificity of 1 (tag selector)
  • .class has a specificity of 10 (class selector)
  • #id has a specificity of 100 (ID selector)
  • p.class has a specificity of 11 (1 for the tag selector and 10 for the class selector)
  • #id .class has a specificity of 110 (100 for the ID selector and 10 for the class selector)

  When there are multiple CSS rules that could apply to an element, the rule with the highest specificity is used. If two or more rules have the same specificity, the rule that appears later in the CSS file is used.

  Understanding specificity in CSS is important for avoiding unexpected styling issues and ensuring that CSS rules are applied correctly to the desired elements.
