I am trying to change the the background color of the stages of an application built on Pega 8.4 as per branding requirement. I tried update stages element from py-portal-stage css in my own overriding CSS which i have configured in the skin rule. But the change is not getting reflected. I performed similar changes in Pega 8.3 with UI Kit and it worked. But its not working in Cosmos UI.
The css you attached has classes applicable to the chevron in UI kit based applications. These classes are not used in the Cosmos based application. You need to change the css. What do you want to achieve with the above styling you mentioned?
