This class is used to parse CSS styles it also compresses styles to reduce the output size.

@example
var Styles = new tinymce.html.Styles({
   url_converter: function(url) {
      return url;
   }
});

styles = Styles.parse('border: 1px solid red');
styles.color = 'red';

console.log(new tinymce.html.StyleSerializer().serialize(styles));
