With the innerHTML method, we can get or set the content of a particular parent element, the inner part.
With the outerHTML method, we will get or set the parent element reference itself.

It's the same as innerHTML method.

var parent_element = someElement.outerHTML;

The variable parent_element will have all the content plus the parent element of that someElement variable.

someElement.outerHTML = "<div id='replacement'>New content</div>";

The variable someElement (which is the representation of a particular DOM element) will all be replaced with the new content plus the wrapper (parent element) declared above.
