Sitejet Builder features two built-in colour schemes for the editor: dark and light. The default setting for this parameter is automatic mode, which detects the theme of the browser and adjusts its colour scheme accordingly. However, it is possible to force a specific editor colour theme regardless of the browser settings. To do this, click the settings icon (three lines) in the left sidebar.
