The new portal has been re-designed from the ground up to work with a responsive design that is optimised for use with a mobile (smartphone) or tablet. It works equally well on a laptop or desktop computer.
Some of the screenshots you may see have been taken from a different size screen than that of the device you are using and may look slightly different.See below:
On a desktop computer or laptop, you will see a menu on the left.
On a mobile (smartphone) or tablet, the menu is replaced with the drop-down "hamburger" menu.
