Issue
I have a strange problem with the Jenkins HTML Publisher plugin, wherein all the fancy CSS I have added to the report is stripped out when viewed in Jenkins. If I download the report to local, I am able to see the CSS formatting. Is there a setting in Jenkins which allows CSS to be viewed?

Solution
Figured out the issue. Sharing it here for other users.
CSS is stripped out because of the Content Security Policy in Jenkins. (https://wiki.jenkins-ci.org/display/JENKINS/Configuring+Content+Security+Policy)
The default rule is set to:
sandbox; default-src 'none'; img-src 'self'; style-src 'self';
This rule set results in the following:
- No JavaScript allowed at all
- No plugins (object/embed) allowed
- No inline CSS, or CSS from other sites allowed
- No images from other sites allowed
- No frames allowed
- No web fonts allowed
- No XHR/AJAX allowed, etc.
To relax this rule, go to
- Manage Jenkins->
- Manage Nodes->
- Click settings(gear icon)->
click Script console on left and type in the following command:
System.setProperty("hudson.model.DirectoryBrowserSupport.CSP", "")
and Press Run. If you see the output as 'Result:' below "Result" header then the protection disabled. Re-Run your build and you can see that the new HTML files archived will have the CSS enabled.
