Formatting source files
Xylescope uses CSS style sheets to format source files

Source files are transformed by Xylescope into HTML internally and then displayed in the HTML Pane and CSS Pane with the help of Safari's rendering engine. Different Editor Style Sheets can be selected by using either the context menus of the HTML and CSS panes or the menu.
It is possible to specify custom CSS style sheets to be used for formatting.
Choose the menu command
or open the preference dialog and select " " to start making changes to the built-in editor sheets or to create new ones. It is strongly recommended to make a copy of existing build-in editor sheets before proceeding on with any custom changes.
