We will need a stylesheet in order to style some things on our Confluence page that cannot be otherwise created with inline styles i.e. hover effects and overlays.
Currently, when I create a class within an HTML Macro and then define the styles for that class in Space Tools > Content Tools > Look and Feel > PDF Stylesheet, nothing happens.

I also tried to create an internal stylesheet within the html macro and this did not work either and in-fact it broke the page:

How can I connect the PDF stylesheet with the HTML Macros on our page? Or is there any other way to import a stylesheet that syncs with the classes within HTML Macros? I'm pretty sure we're on the Confluence server.
Thanks
