We have a live application which was utilizing the .tablet-show, .tablet-hide classes which I believe were part of Calcite-Web which is now deprecated. This has made my application no longer mobile friendly and I am not finding this functionality on the calcite components in the rest of the documentation. I tried updating to different versions of the SDK and Design System,and that did not help.
Here is the live site to see the issue.
Do you all have a similar function class or a recommendation to correct this? I hid mobile on our live site, but here is a git-hub page showing the bug.
