HTML | DOM outerHTML property

The outerHTML property of the DOM interface gives the HTML fragment of that element. It not only gives the content, but the whole HTML structure of the element. It can also be used to replace the HTML structure of the element.

Syntax:

  • To return the outerHTML.
    var value = element.outerHTML;
  • To set the outerHTML.
    element.outerHTML = "HTML_Structure";

Return value: When getting outerHTML, it returns HTML String data.
