Can I have inline styles for Facebook Instant Articles articles? I have looked for it on their documentation for design guides, they didn't specify if we can or cannot. I know with Google AMP, we were not able to use it, I am not sure if the same applies here.
It appears that no we cannot add inline styles, however, we can wrap those elements with <iframe> and apply inline styles to those elements and FB will pick it up. E.g:
<iframe> <div style="background: red; color: red">Text on Red</div></iframe>
