The :first-child CSS pseudo-class represents the first element among a group of sibling elements.
/* Selects any <p> that is the first element
among its siblings */
p:first-child {
color: lime;
}
Note: As originally defined, the selected element had to have a parent. Beginning with Selectors Level 4, this is no longer required.
