// A collection of mixins and CSS classes that can be used to apply elevation to a material

// See: https://material.io/design/environment/elevation.html
// Examples:
//
//
// .mat-foo {
//   @include $mat-elevation(2);
//
//   &:active {
//     @include $mat-elevation(8);
//   }

// For an explanation of the design behind how elevation is implemented, see the design doc at
// https://goo.gl/Kq0k9Z.

// Colors for umbra, penumbra, and ambient shadows. As described in the design doc, each elevation
// level is created using a set of 3 shadow values, one for umbra (the shadow representing the

// space partially obscured by an object), and one for ambient (the space which contains the object
// itself). For a further explanation of these terms and their meanings, see
// https://en.wikipedia.org/wiki/Umbra,_penumbra_and_antumbra.

// created by taking a few reference shadow sets created by Google's Designers and interpolating
// all of the values between them.

// A collection of mixins and CSS classes that can be used to apply elevation to a material
// element.
// See: https://material.io/design/environment/elevation.html
// Examples:
//
//
// .mat-foo {
//   @include $mat-elevation(2);
//
//   &:active {
//     @include $mat-elevation(8);
//   }

// https://goo.gl/Kq0k9Z.

// Colors for umbra, penumbra, and ambient shadows. As described in the design doc, each elevation
// level is created using a set of 3 shadow values, one for umbra (the shadow representing the

// space partially obscured by an object), and one for ambient (the space which contains the object
// itself). For a further explanation of these terms and their meanings, see
// https://en.wikipedia.org/wiki/Umbra,_penumbra_and_antumbra.

// created by taking a few reference shadow sets created by Google's Designers and interpolating
// all of the values between them.
