How to use the html() method in jquery

In JavaScript, the usage of the "html()" method is "element.html (new content of the selected element)". The html method sets or returns the content of the selected element. When this method is used to return content, the content of the first matching element is returned; when this method is used to set content, the content of all matching elements is rewritten.
