Using stylesheets and javascript in your course

The Moodle oppia export block comes by default with a stylesheet and javascript file that will be applied to any courses you export - so the stylesheet, javascript and related resources (images etc) will get exported to the course package too.

You can see examples of the default.css stylesheet and javascript at Default Styles provided by default.css

Creating your own style

To add a new style (or adapt the existing one), create an new css file in the <block>/styles directory, along with a new directory for the resources (see the current folder structure).
