The :only-of-type
CSS pseudo-class represents an element that has no siblings of the same type.
/* Selects each <p>, but only if it is the */ /* only <p> element inside its parent */ p:only-of-type { background-color: lime; }
Note: As originally defined, the selected element had to have a parent. Beginning with Selectors Level 4, this is no longer required.
