This article is part 1 of a series in which Gergely Orosz is going to cover everything that worths knowing about styles in Silverlight 4.
Styles in Silverlight are a powerful mechanism that allow controlling the visual representation of elements in a unified way for all user interface elements. The concept is similar to using CSS to control the look and feel of HTML.
Style properties differ by element type. For example on a TextBlock (a text element) one can style the FontSize, FontFamily, Foreground and lots of other properties. On an Ellipse however none of these properties can be set, on the other hand it does provide for example the Fill property, that the TextBlock does not.
