Zero width columns for Zurb Foundation grid. Used instead of Foundation's visibility classes because they can force some display properties that are undesired on the hidden element. Also, just feels more natural.

.small-0 { display:none; }

@media #{$small} {
	.medium-0 { display:none; }
	[class*="medium-"]:not(.medium-0) { display:block; } // resets the .small-0 display property
}

@media #{$medium} {
	.large-0 { display:none; }
	[class*="large-"]:not(.large-0) { display:block; } // resets the .medium-0 display property
