 ## Referencing Resources
 
-To reference an application resource in a project, use the "$r('app.type.name')" format. app indicates the resource defined in the resources directory of the application. type indicates the resource type (or the location where the resource is stored). The value can be color, float, string, plural, or media. name indicates the resource name, which you set when defining the resource.
+To reference an application resource in a project, use the ```"$r('app.type.name')"``` format. **app** indicates the resource defined in the resources directory of the application. **type** indicates the resource type (or the location where the resource is stored). The value can be color, float, string, plural, or media. **name** indicates the resource name, which you set when defining the resource.
 
-When referencing resources in the rawfile sub-directory, use the "$rawfile('filename')" format. Currently, $rawfile allows only the <Image> component to reference image resources. In the format, filename indicates the relative path of a file in the rawfile directory, and the file name must contain the file name extension. **NOTE** that the relative path cannot start with a slash (/).
