First of child type selector.

Shorthand version  $(':first-of-type')

Description

The :first-of-type selector, selects the first element types that have no other element with both the same parent and the same element name coming before it in the document tree.

  • If this selector is not preceded by another selector, the universal selector ("*") is implied and so the whole DOM will be searched. Use another selector as in the examples below to narrow the search and improve performance.
