I am trying to make css isolation for Blazors QuickGrid component. When I use the pseudo selector "::deep" it gives we the warning: " Unknown pseudo selector 'deep'". How can I fix this and is it possible when using Rider Jetbrains IDE?
::deep th.country-name { width: 14rem; }
/* Subtle stripe effect */
::deep tr:nth-child(even) {
background: rgba(255,255,255,0.4);
}
/* Don't collapse rows even if they are empty */
::deep tbody tr { height: 1.8rem; }```
