Rendering Text

On Web you're able to render text anywhere in the DOM, on iOS & Android you can only render text inside a <Text /> component. Blocks adheres to this convention, meaning that any text must be wrapped in a <Text /> component.

Outline / Border

Border is supported on Web, iOS and Android. Outline is only supported on Web. Therefore blocks only supports border at this present time.
