-1. Logical px set by <length>:
-   1. The default logical screen width is 720 px (for details, see the "window" section in [config.json](js-framework-js-tag.md)). Your page will be scaled to fit the actual width of the screen. For example, on a screen with the actual width of 1440 physical px, 100 px is displayed on 200 physical px, with all sizes doubled from 720 px to 1440 px.
-   2. If you set autoDesignWidth to true (for details, see the "window" section in [config.json](js-framework-js-tag.md)), the logical px are scaled based on the screen density. For example, if the screen density is 3x, 100 px will be rendered on 300 physical px. This approach is recommended when your application needs to adapt to multiple devices.

+A struct decorated by **@Component** has the componentization capability and can serve as an independent component. This type of component is also called a custom component, and its UI structure is described in the **build** method. Custom components have the following features:

 - Reusable: Custom components can be reused by other components and used as different instances in different parent components or containers.
