/// Removes the element's gutter margin, regardless of its position in the grid hierarchy or display property. It can target a specific element, or every `nth-child` occurrence. Works only with `block` layouts.

/// @param {List} $query [block]
///   List of arguments. Supported arguments are `nth-child` selectors (targets a specific pseudo element) and `auto` (targets `last-child`).
///
///   When passed an `nth-child` argument of type `*n` with `block` display, the omega mixin automatically adds a clear to the `*n+1` th element. Note that composite arguments such as `2n+1` do not support this feature.
///
///   **Deprecation warning**: The omega mixin will no longer take a `$direction` argument. To change the layout direction, use `row($direction)` or set `$default-layout-direction` instead.
