Hey @nadim.
Thanks for sharing your experience.
While using the *-child pseudo class will reflect your styles accordingly on the front-end, one needs to know that the back-end might show some inconsistencies.
You can read about this issue here.
Targeting elements more precisely with the *-of-type pseudo class instead will result in a more consistent experience.
I know it’s not an optimal solution, but we will probably (well, hopefully) see improvements in that regard down the road.
