The HTML players normally add CSS class names to the HTML generated for each page element. These are the same class names that template designers can use in the .css files that they create. See Tags for questionnaire items for more information.

CSS class names are not added to the rendered HTML if the layout template includes an mrPage element with the IncludeCSSNames attribute set to False. This reduces the amount of HTML code sent to the browser. See Sub-templates for more information.
