Examples

Basic

.card {
  min-width: rem-calc(64px);
}
 
.card {
  min-width: rem-calc(64);
}

Overriding the rem base

Default base is 16px but you can override it at any time (here with 12px):

.card {
  padding: rem-calc(20px, 12px);
}

You can also act globally on the rem base, using:

@rem-base: rem-base(10px); // will globally override the rem base. 
 
.card {
  min-width: rem-calc(20px); // is now equivalent to rem-calc(20px, 10px); 
}
