Previewing and displaying lessons
To see how the page looks in different layouts, simply open it in the Presentation view (e.g. click View as and select Presentation). Changing the size of the browser window will allow you to display the page in prepared layouts.
You can also preview changes in the Embed view, but it is necessary to reload the page after changing each window size. This is because there are no scaling mechanisms in this view – we get the layout in its pure form.
