Inspired by the types of tabs which are becoming more commonplace in web-design, the Tabs condenses information from a number of elements into a single element on a mobile device (iOS).
A desktop will display a set of rows and columns of information. A mobile will refactor these elements into what is essentially a small carousel, allowing the user to control the view of the content, and toggle through appropriately.
The Tab increases engagement with content on a mobile device because it invites the user to interact with it. It also has a practical advantage of reducing the length of an email significantly, wherein a number of items of content is reduced to the space of just one. Support is currently only in iOS. The current breakpoints set-up means that it does not currently activate on iPad. Desktops show the desktop version, without any complications.

| Android (Galaxy S6) |
| S6 does not support the absolute positioning required, and so causes the carousel to break. The email flows like the content usually would without the carousel functionality. |
| iPhone/iPad |
| None. The current functionality does not extend to an iPad, but may be modified to include tablet sizes. Fully supported |
| Windows (Nokia Lumia) |
| The control of siblings and child elements in CSS has support, but is inconsistent in application. The email flows like the content usually would without the carousel functionality. |
