The interesting feature on this site is a form which allows a user to request a quotation for the replacement of misted glass double glazing units.

For each window, the location,  measurements plus type of glass need to be specified for each window that needs de-misting. This makes for quite a complex form and it needed to work sensibly on all devices. We managed it, although you have to turn a phone into landscape mode if you want to be able to read the writing!
