 ## How It Works
 
-Container queries rely on there being an ancestor control being set as a container. Changes to the size of the container activate styles based on queries. Those queries can check either the width or height of the container, or both. Any control can be a container, but a control set as a container can not be affected by styles hosted by a container query linked to it. When a query is activated, all styles hosted in the query will also be activated based on their selectors.

 * `Normal`: The container's size isn't queried. This is the default value. The control follows normal measurement and arrangement.
 * `Width`: The container's width is queried. The container will use the maximum width allowed by its parent, and that value is used in all related container queries. In most cases, the final width is the max width allowed.
 * `Height`: Same as `Width`, but only the container's height is queried.
 * `WidthAndHeight`: Both width and height of the container is queried.
