Customizing the tool

Changing model appearance using cascading style sheets (CSS)

itemis Model Viewer controls the visual appearance of model elements by way of cascading style sheets (CSS). The tool has a built-in CSS style sheet called Standard. However, you can provide your own styling rules in the form of CSS files. Figure "Customizing model representation using cascading style sheets" is showing an example.
