Default stylesheet is hidden from view in the Manage Stylesheets module (this is not available to change by users, removed for clarity)
Version 4.5.29
Style sheets are a quick way to apply text and background colours to a script version. You can also add a logo or background image. Any additional styling at control level will over ride the settings applied to the script version using a style sheet.
To Edit a stylesheet, click on the stylesheet name and then edit the stylesheet elements in the right hand panel. See next page for more details.
To add a stylesheet, click the "Add new" button at the foot of the list of existing stylesheets, give the style a name and then edit each element.
You cannot delete a stylesheet in the application, only from the database, however you can re-name them.
