/// ## Overview
|
|
/// If you want to generate svg-backgrounds
|
|
/// for help visualizing and debugging your grids,
|
|
/// import the SVG Grid Plugin.
|
|
///
|
|
/// The plugin adds `svg-grid-colors` setting
|
|
/// to your global defaults,
|
|
/// which you can override in `$susy`.
|
|
/// It also provides you with a new function,
|
|
/// `susy-svg-grid()`,
|
|
/// which will return inline svg for use in
|
|
/// backgrounds or generated content.
|
|
///
|
|
/// This function come with an unprefixed alias by default,
|
|
/// using the `svg-grid` import.
|
|
/// If you only only want prefixed versions of the API,
|
|
/// import the `svg-grid/prefix` partial instead.
|
|
