The DevExpress MVC HTML Editor provides Custom CSS options that allow you to deliver custom formats as defined by custom CSS classes - exposed to end-users and applied to the content selected within the editor. By using the Custom CSS feature of the DevExpress MVC HTML Editor, logical elements (such as titles, headers, text blocks, etc) can be formatted using individual formatting styles, defined by names of the associated CSS class and HTML tag.
In this demo, custom styles are defined for content text elements such as article title, headers, the main content text and image titles. To apply any of the predefined styles to the text selected within the Design View, choose the desired style item within the "Apply CSS" bar item.
The standard toolbar's "Apply CSS" dropdown editor (ToolbarCustomCssEdit type) allows you to list available custom CSS styles and make them available to end-users.
