Syntax: .prev(selector)
Parameters:
| Parameter | Description |
| selector | String value, containing the selector expression used to match elements. |
Description: If given a jQuery object that represents a collection of DOM elements, the .prev() method allows us to search for these elements in the DOM tree. The previous sibling element and constructs a new jQuery object with the matching element.
