I don’t think this module gets enough love. I use it to separate the overlap between placement of modules in my Magic Mirror. To me, this module is invaluable. My Hue lights were overlapping the Now Playing from Roon so I inserted a 150px space with the MMM-Space module and viola, no overlap.
Thanks to the author!
@doctorwhen it’s a good solution (for beginners) but one that can be done with one line of css instead of installing a module.
