To add a close button to a page in your course:
Open the Page you would like to add your close button to and select Layout -

Click the orange 'Add here' button where you would like to add your close button -

Select Buttons and Icons -

...and then Button Holder -

This will contain a Link button by default.
To change this to a Close Course button, click one of the orange 'Add here' buttons in the Button Holder you have just added, for example here:

Select Close Course Button -

You can then delete the Link button if this is not needed!
💡 Please note the close course button will only close the course if the course has been opened in a new tab or window.Â
