rem() is a Sass mixin that converts pixel values to rem values for whatever property is passed to it. It returns two lines of code — one of the regular pixel values (for some older browsers), and another with the converted rem values (for everyone else).

Sample input:

.element {
  @include rem('padding',10px 0 2px 5px);
}

Sample output:

.element {
  padding: 10px 0 2px 5px;
  padding: 1rem 0 0.2rem 0.5rem;
