How to make a style WBB 4 and WBB 4.1 ​compatible?

  • How do we go about making a style that is compatible with both versions WBB 4 and WBB 4.1? How much has the CSS changed between these versions?

  • My Design Tool is predestined for this:
    Design-Werkzeug


    There you can find all elements of both Burning Board 4.0 and Burning Board 4.1. However, if you edit templates, you have to look for changes made form Burning Board 4.0 to Burning Board 4.1. If there have been made changes, you can’t create a style, which is compatible for both versions. Then you have to use two versions.
