The innerHTML property will return to us
all the HTML that is nested inside the element.
The outerHTML property, on the other hand, will
return to us not only the HTML that is nested
inside the element, but also the element itself.
The result in the console shows us
that for getting the element as well as
the nested HTML inside it, we should use outerHTML.
But to get only the nested HTML inside an
element, we can use innerHTML.
