Hello All,

I am very new to Lightning development and salesforce in general.

I am trying to make a simple component that consists of tabs with a graph in each one. I have directly copied and pasted the example of a simple tabset from (https://developer.salesforce.com/docs/component-library/bundle/lightning:tabset/example) 

My issue is that the styling looks like it is entirely missing. Below is a picture of the result: 


I have noticed that I am getting an error that may or may not be related to this but I have been unable to find anything about it other than to modify our CSP which doesn't sound right to me. paste of the  error below: 

Refused to run the JavaScript URL because it violates the following Content Security Policy directive: "script-src 'self' 'nonce-[removed as im not sure if this is sensitive]' chrome-extension: 'unsafe-inline' 'unsafe-eval' https://sfdc.azureedge.net *.cs19.visual.force.com https://ssl.gstatic.com/accessibility/". Note that 'unsafe-inline' is ignored if either a hash or nonce value is present in the source list.

This error is repeated each time I click on an item in the tabset.

Has anyone had this issue or know what is possibly causing it? Any help would be greatly appreciated.

Thanks,
Travis
