-    // providing a property multiple times, for browser compatibility
-    // reasons.
-    //
-    // A property in a style object can also be a sub-selector, which

-    // selector. Such a property should contain a `&` character, which

-    // styles defined inside the object that's the property's value. For
-    // example to create a media query you can do `{"@media screen and
