You’re very welcome.
Okay was taking a look here on Meta with Graceful theme selected. On mobile for some reason there are no colored bars like in desktop. I myself am not sure why.
Though on desktop in the sidebar switch it to mobile view and should be able to use inspect element. I would also check on desktop mode and see how the CSS differs. If needed can likely create a custom component with overrides in Mobile to get the colored bars working as expected.
