I guess so.
Here my test:
- Create a theme:
card-mod-more-info-yaml: |
ha-more-info-history $: |
.header {
color: red;
}
.: |
ha-more-info-history {
--secondary-text-color: orange;
}
2.Open more-info popup, switch to the 2nd tab - the color: red
is not applied, the scale is orange:
3. Update the theme - run service: frontend.reload_themes
.
4. Check that the header now is red:
5. Switch to the 1st tab, next back to the 2nd tab - the header is again of standard color.
