In my first time implementing Radium, I am trying a simple ':hover'. Here is what I have ...
import React from 'react'
import Radium from 'radium'
@Radium
export default class ResSideNav extends React.Component {
  render() {
    const style = {
      navItem: {
        backgroundColor: '#2c80b8',
        ':hover': {
          backgroundColor: '#3A94CF'
        }
      }
    };
    return(
      // navItems defined elsewhere
      <div style={ style.navContainer }>
        {navItems.map((item, i) => <div key={ i } style={ style.navItem }>
                                    { item.name }</div>)}
      </div> 
    );
  }
};
I am getting no errors in server or console, there is just flat out no :hover state event. Webpack is giving me no errors as I have setup my .babelrc and Webpack Config File to read decorator syntax.
Just to be clear, there are other styles and elements at play, but this is a trimmed fat example. Thanks.
