// This file contains style definitions that can be used by CKEditor plugins.
//
// The most common use for it is the "stylescombo" plugin which shows the Styles drop-down
// list containing all styles in the editor toolbar. Other plugins, like
// the "div" plugin, use a subset of the styles for their features.
//
// If you do not have plugins that depend on this file in your editor build, you can simply
// ignore it. Otherwise it is strongly recommended to customize this file to match your
// website requirements and design properly.
