Styles

Fvwm styles, defined in the configuration file, control the appearance and behavior of windows and other elements within the Fvwm window manager. They allow for customization of window decorations, focus behavior, and more. Matching window properties like name, class, or resource allows for targeted styling.

A Colorset is a collection of colors: foreground (fg), background (bg), hilight (hi), and shade (sh). The foreground is the color of the text, background is the color behind the text, and the hilight and shade are used to give a 3D beveled effect around the border. This causes a raised or sunk look, like a button. Besides just setting the color, Colorsets can use pixmaps, gradients, shape masks and be pseudo-transparent.
