To update the theme, the customised Docker image needs to be updated to include that code. There is a job to rebuild in Jenkins https://build-hee.transformcloud.net/jenkins/job/keycloak-docker/

Styling updates to keycloak theme

It is possible to tweak the styling for a keycloak theme without having to run keycloak locally via using charles https://www.charlesproxy.com/download/ which is a web proxy application. This is achieved by locally mapping the remote css file responsible for the theme to a local css file on your computer. 

For example the remote css file https://stage-apps.lin.nhs.uk/auth/resources/2.2.2.final-snapshot/login/lin/css/login.css can be mapped to /Users/XXX/Sites/HEE/keycloak/themes/lin/login/resources/css/login.css which essentially means you can locally work on the css and once done can push your changes to the git repo mentioned above as well as triggering the jenkins job thats also mentioned above.
