Layers

The layers property allows you to define an ordered set of layers. These layers can later be referenced using the layer property. Layers control the order in which widgets are painted on screen. More information on layers can be found in the guide.

Syntax

layers: <STRING> ...;

Example

In the example below, #box1 is yielded before #box2. However, since #box1 is on the higher layer, it is drawn on top of #box2.

=== "Output"
