				This is a default featherlight lightbox.<br>
				It's flexible in height and width.<br>
				Everything that is used to display and style the box can be found in the <a href="https://github.com/noelboss/featherlight/blob/master/src/featherlight.css">featherlight.css</a> file which is pretty simple.
