Scrim¶
A scrim is a temporary effect applied to a surface for the purpose of making content below it less prominent.
Examples¶

A scrim being used to indicate that a drawer is modal.¶

A scrim being overlaid on an image to allow a readable caption on top of it.¶
Is this the right control?¶
Most controls that require scrims will apply one themselves, such as drawers.
Manually apply scrims only when:
Content would not be legible without them.
Modal controls are overlaid on content.
