/// @param {Keyword|Number} $size [$grid-row-width] Maximum size of the row. Set to `expand` to make the row taking the full width.
/// @param {Number} $columns [null] - Number of columns to use for this row. If set to `null` (the default), the global column count will be used.
/// @param {Boolean} $base [true] - Set to `false` to prevent basic styles from being output. Useful if you're calling this mixin on the same element twice, as it prevents duplicate CSS output.
/// @param {Boolean} $wrap [true] - Set to `false` to have row wrapping behavior set to nowrap
/// @param {Number|Map} $gutters [$grid-column-gutter] - Gutter map or single value to use when inverting margins, in case the row is nested. Responsive gutter settings by default.
