If you need to define an additional helper class, you can add a Cascading Style Sheet (CSS) file to your application skin. You can define a helper class for a cell, a layout, or both. The helper class that you define is then available from the helper class picker on the Properties panel.

1. Create the CSS helper class in a CSS file.

2. For each helper class, add a comment before the CSS Selector:

   1. For the type, enter helper-class.

   2. Enter a name.

   3. Enter a category of layout or cell. If the helper class can be used for either category, enter layout,cell.

   4. Enter a description on a single line, as shown in the following example:

      /**************Type: Helper-className: text-primaryCategory: cellDescription: primary styling for text**************/

3. On the Included styles tab of the Skin form, attach the CSS file as an additional style sheet in your application skin. For more information, see Included styles.
