Which browsers and devices work best?

Browsers

Lessons are built for modern browsers. A recent version of Chrome, Edge, Firefox or Safari works well. Keeping your browser up to date fixes most display problems before they start.

Devices

A desktop, laptop or tablet gives you the best experience, because the lessons are hands-on and most exercises are easier with a proper screen.

Reading a lesson back on your phone is fine. Building a spreadsheet on one is character-building. Save the practical work for the bigger screen.

If something misbehaves

First, refresh the page. Next, check for a browser update. If the problem is still there, email hello@oba.uk and tell us what you were doing, what you expected and what happened instead. A screenshot helps a lot.
