How to use Static Content Macros

I’m currently looking into static content macro but having some difficulty to understand what I should use it for. So far I haven’t been able to set any CSS besides the one directly on the elements and all elements added to the .hbs file which needs an action to work, for example <button>, are removed during rendering.
Am I missing something or am I only supposed to be able to add text and images and do some minor manipulation?

Dear Jenny,

you can only return Confluence Storage Format with a Static Content Macro. For all other things you need a Dynamic Content Macro. I hope that helps.
