Conditional Styling is performed in a very similar manner to dynamic hiding and showing of fields. Under different styling sections on the Page Details tab there are options to Add Conditional Styling. For each of these that you click you will be prompted for an XPath when you visit the Data Bindings page. Again, you can construct an arbitrary XPath to determine when to apply the dynamic styles. These styles can be specified in-line or you may choose CSS class names from your CSS.
