/// Specifies the number of columns an element should span. If the selector is nested the number of columns of its parent element should be passed as an argument as well.
///
/// @param {List} $span
///   A list containing `$columns`, the unitless number of columns the element spans (required), and `$container-columns`, the number of columns the parent element spans (optional).
///
///   If only one value is passed, it is assumed that it's `$columns` and that that `$container-columns` is equal to `$grid-columns`, the total number of columns in the grid.
///
///   The values can be separated with any string such as `of`, `/`, etc.
///
///   `$columns` also accepts decimals for when it's necessary to break out of the standard grid. E.g. Passing `2.4` in a standard 12 column grid will divide the row into 5 columns.
///
/// @param {String} $display [block]
///   Sets the display property of the element. By default it sets the display propert of the element to `block`.
///
///   If passed `block-collapse`, it also removes the margin gutter by adding it to the element width.
///
///   If passed `table`, it sets the display property to `table-cell` and calculates the width of the element without taking gutters into consideration. The result does not align with the block-based grid.
///
/// @example scss - Usage
///   .element {
///     @include span-columns(6);

///    .nested-element {
///      @include span-columns(2 of 6);
