Looking for an Alternative to Boom Theme Panel in Grafana 11.6

Hi Grafana Community,

I’m currently using the Boom Theme panel , which I understand is deprecated as of Grafana version 11.6. This panel was very useful for me because it allowed HTML and custom CSS for theming purposes. Specifically, I used it to dynamically change the background color and font of other panel headers based on custom logic.

Here is a snippet of the CSS I use:.panel-title-container[data-testid=‘data-testid Panel header NOM DOMAINE’] {
background-color: rgb(31, 96, 196);
color: rgb(225, 235, 235);
}

This customization is essential in my dashboard for visual grouping and clarity.
Attached is a screenshot showing how I configured this within the Boom Theme panel.

:backhand_index_pointing_right: Is there any recommended alternative or workaround in Grafana 11.6+ that would allow me to achieve similar visual theming across panels?
Ideally, I’m looking for a solution that allows injecting or applying CSS conditionally or globally based on panel titles or tags.

Thanks in advance for your help!

You should be able to accomplish it using Business Text panel

Okay, but I can’t target another panel from the Business Text panel like I used to with this code: .panel-title-container[data-testid='data-testid Panel header NOM DOMAINE'] .
