 If you are using in-app acrylic on navigation surfaces, consider extending content beneath the acrylic pane to improve the flow on your app. Using NavigationView will do this for you automatically. However, to avoid creating a striping effect, try not to place multiple pieces of acrylic edge-to-edge - this can create an unwanted seam between the two blurred surfaces. Acrylic is a tool to bring visual harmony to your designs, but when used incorrectly, can result in visual noise.

 ## Do's and don'ts
 * Do use acrylic as the background material of non-primary app surfaces like navigation panes.
 * Do extend acrylic to at least one edge of your app to provide a seamless experience by subtly blending with the app’s surroundings.

 * Don’t place in-app and background acrylics directly adjacent to avoid visual tension at the seams.
 * Don't place multiple acrylic panes with the same tint and opacity next to each other because this results in an undesirable visible seam.
 * Don’t place accent-colored text over acrylic surfaces.
