Traditional UI

Support for reflow and responsivity was not a largely considered for Traditional UI when it was originally built. With various possible combinations of elements on the UI between applications, users may experience visual responsivity issues on certain screens when increasing their browser zoom levels.

However, some targeted changes have been implemented to support reflow and responsivity where possible. In the Platform '23 release, enhancements were made to parts of Cosmos applications to support zoom levels up to 400% in modal dialogs and case view screens. The following image shown an example of a modal dialog in a Cosmos app when viewed at reflow dimensions 320x256 pixels:

As a general rule of thumb, users can typically increase browser zoom to around 200% before encountering potential issues with page responsivity in Traditional UI applications. This zoom value may vary depending on the innate dimensions of their viewport.

Constellation UI

Looking forward, the modern Constellation UI was developed with a strong emphasis on responsivity between various dimensions and zoom levels, and better support for accessibility in general.  Constellation applications have been designed to support reflow between pages, providing a more seamless user experience.

Following is an image of a case view screen when viewed at 320 x 256 pixels:

Similarly we can see how the Tasks list on the Home screen of a Constellation application is responsive when viewed at the same dimensions:

Overall support for reflow is significantly more robust in Constellation UI compared to Traditional UI. With Constellation being directionally the path forward in modern capabilities, performance, and wide support for accessibility, we are iteratively updating and continuing to address any issues with reflow and responsivity as they are identified for consistency across applications.
