Add loader for React-Flexbox-Grid into Webpack2 config - reactjs

Question

I have tried endlessly to integrate a loader for React-Flexbox-Grid into my web pack config (shown below), but I receive error:
errors — client:119./~/flexboxgrid/dist/flexboxgrid.css
Module parse failed: /Users/---project-path---/node_modules/flexboxgrid/dist/flexboxgrid.css Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
This is the first time I have had to add in something like this, so I am not sure if I have been adding the 'include: /flexboxgrid/' in the correct place (I added it under the development/production rules), but it just returns the same error! Clearly what I am doing is wrong.
ps. I am using react-redux-webpack2-boilerplate

Its better to transform class properties.This kind of loader will help to solve this
{
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/,
loader: 'babel-loader',
query: {
presets: ['react', 'es2015', 'stage-0'],
plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy'],
}
}
