FontUnit Structure
Assembly: System.Web (in system.web.dll)
For a list of initial property values for an instance of FontUnit, see the FontUnit constructor.
The following code example demonstrates how to use a Style object to change the style properties for multiple controls at one time. Each time one of the Style property values changes, each control must call its ApplyStyle method. Not all the controls included in this example support all the properties that are demonstrated. If a control does not support a particular property, the appearance of the control will not change when the property value is changed.
