Banned inline style CSP and dynamic positioning of HTML elements

Question

A client has changed their CSP to ban inline styles on their server. As far as I can tell, this means that we can no longer use JS to dynamically position/animate/style HTML

Answer 1

JavaScript is executed on the client. Unless the filtering software is incredibly clever, you can still add dynamic inline styles as the server has no idea what's happening in the browser. What you can't do, however, is add inline styles as part of the HTML you send to the client.
