If the style item to add exists in the HtmlTextWriterStyle enumeration, use the overload of the Add method that takes an HtmlTextWriterStyle parameter because it is strongly typed. This means that items that are added will be included when viewing items with the get accessor of the Item property.
The following code example demonstrates how to use both overloads of the Add method to add a cascading style sheet to an HtmlSelect, HtmlInputSubmit, and a Label control programmatically.
