Tsarin haɗin gari yana da mahimmanci (LVHA): :link, :visited, :hover, :active.
li:first-child { } /* first li among its siblings */
li:last-child { } /* last one */
li:nth-child(2) { } /* the 2nd */

Pseudo-classes ba ka iya yin siffa hulƙuntar (hover/focus — mahimmanci ga UI mai amfani, aiki) da tsari (raba, farko/karshe) ba tare da ƙarin markup ko JavaScript ba.
Waɗanda ke zamani (:has, :is, :focus-visible) suna warwarewa matsaloli da a baje jiya suke buƙatan JS ko zaɓabuwan karuwa.
