The article discusses the utility of the :is() pseudo-selector in CSS, highlighting its ability to enhance the readability of compound selectors. However, it cautions users about its specificity matching the most specific argument used. In contrast, the :where() selector provides similar functionality without the specificity issues, always carrying a specificity score of zero. This makes :where() a preferable choice when the goal is to maintain control over specificity while enjoying the simplicity of compound selectors.
The :is() pseudo-selector simplifies complex CSS selectors for enhanced readability, but be cautious as its specificity can match the most specific selector in its list.
By utilizing the :where() selector, you can achieve similar results without the specificity concerns inherent in the :is() pseudo-selector, thus resetting specificity.
