Issue:
CSS styles responsive and supporting themes
Hello
I started using dynamictext-panel which is great but i'm struggling with making css responsive to grafana dark/light theme
for example i want to have text color in "blue" on light theme and "white "(or default) on dark theme
Can you provide an example of how to do this
This will help to provide consistency on a mixed dashboard with other visualisation Types
Thank you
