Hi All,

 

I have used form header component in workspace in that component used label value component. I want to modify the font-size and font-weight in both component. Could you please let me know how can I change the CSS. I tried by adding below CSS, but seems it's not getting applied to the component.

HI @pallavigaik ,

The Record Header contains some elements that are inside the Shadow DOM, so their styles cannot be modified directly using standard CSS in ServiceNow UI Builder.
