This page contains more technical parameters:
Custom Script (js). If you need to include an external js library to your project, define HTML <script> here.
For example <script src=“/js/myscript.js"></script>
Custom Head (js). If you need to include an external CSS file to your project, define HTML <link> here.
For example <link rel=“stylesheet” href=“/css/mycss.css"></link>
External Scripts or CSS won’t be loaded within the TB Editor, they will be loaded (and executed) only when running the project.
