Can I customize/override the Grafana Style sheet?

I am planning to customize the way grafana looks esp the colours for different applications , is there any way that I can customize the CSS or override the css classes that are currently existing ? Can I pass a style sheet that could override during run time ?

no this is not possible. You need to fork Grafana and do a full custom build to modify the styles.

Is there any other solution to embedded grafana graphs to match the application UI ? I see that snapshot.raintank.io is available but that’s not serving my purpose. Can I run this locally and embed the same ?

There is no other solution? Neither use a plugin that uses different classes?
