ERROR when trying the layout example from the react-toolbox website

[kavaro]

When trying the "http://react-toolbox.com/#/components/layout" example in create-react-app application I get the following error:

ERROR in ./~/css-loader?importLoaders=1!./~/postcss-loader!./~/react-toolbox/lib/button/theme.css
Module build failed: Error: composition is only allowed when selector is single :local class name not in ".raised", ".raised" is weird

It seems to me the issue is because how you import the module with the create-react-app. For example, to import Button:
Instead, import { Button } from 'react-toolbox';
Try, import Button from 'react-toolbox/lib/button/Button';

Yes!!, this indeed solves the issue.

Many thanks, ....
