For example where there are 3 columns in the navigation this will reduce to 1 or 2 depending on the width of the device you are using. On a PC or Laptop you will see 3 columns, but on a Smartphone it will be displayed as a single column.

To make things easier on a Smartphone the images are resized to cut down on space taken or even removed altogether and some of the additional menu features are also removed so they don't get in the way.

Unfortunately our website is made up of a number of separate websites in order for us to provide all the information. Some of these sites don't work in this responsive way, we are working with our suppliers to rectify this situation so that no matter what type of device you use or the section of the website you are in you will get the information correctly displayed.
