Scopes
Responsive
        Append the responsive scope to the front of any utlity to make
        that utility apply to that size and larger (with the exception of sm which makes that utility only apply to sm size).
    
Responsive Container
        A class is also generated to allow the responsive nature to be defined by the container. To simulate the size of the browser on a container add [size]-container (ex. sm-container).
    
.md-container
                sm:width-1/2
                .sm-container
                sm:width-1/2
                <div class="sm-container bg-blue bg-opacity-10 pad">
    <code>.sm-container</code>
    <div class="width-full sm:width-1/2 height-50-px bg-green bg-opacity-50">
        <code>sm:width-1/2</code>
    </div>
