Change canvas style

Hi there,

I have some question about canvas style, in this case i have config like this.

var editor = grapesjs.init({
    container : '#gjs',
    canvas: {
        styles: ['/builder/css/builder-desktop.css']
    }
})

By default i use css with name builder-desktop.css for default canvas style. And then i want if i change Device Manager and choose mobile, i can change a canvas style to builder-mobile.css.

Thank you very much
