Also, if you are developing something (unclear since the lack of information of your topic) take a look at our new mobile/desktop breakpoint system: > [@Designing for Different Devices (Viewport Size, Touch/Hover, etc.)](https://meta.discourse.org/t/designing-for-different-devices-viewport-size-touch-hover-etc/367810): > > This document outlines the APIs used to adapt Discourse’s user interface for different devices.
