The first is what symbol to use for the ‘close button.’ By default, the “×” character is used. You can change this to any character you like, or even to the word “close” or a blank space.

There is also what we call a “breakpoint” value, this is the smallest number of pixels in width you want the popup. If the screen the user is using is smaller than this number, instead of a popup, the user will be taken to the link target itself. The default is 768, so by default, a smartphone and most tablets will not show a popup, it will go to the link. You can put any value in this location, including zero.
