Cascading style sheets (CSS) are a standard feature of HTML that allow you to define global formatting parameters that can be applied to any number of templates. It is therefore possible, for example, to have a set of completely different page layouts that all have green, 12-point Arial question texts, and to change them all to blue, 14-point Times New Roman question texts simply by changing the specification for the question text in the CSS.

The benefit of using cascading style sheets is that it allows you to simplify the content of your templates by placing tags that are common to all templates in [INSTALL_FOLDER]IBM\SPSS\DataCollection\7\Interviewer Server\ Projects, rather than repeating them in every template. This, in turn, makes it very easy to keep the templates up to date if you need to change the color, font or point size of the text. Note that you will probably need to copy the .css files to the appropriate locations on your web servers if they are to be picked up during interviews.
