Hey Sil, thanks for responding.

There’s a whole host of differences between functional CSS and inline styles, here are some of the more critical ones:

• Inline styles don’t respect media queries, which basically rules out responsive design
• Inline styles aren’t limited to pre-defined options, this is critical because half of the value of functional CSS is to improve consistency in an application by forcing you to use a limited palette of colours, spacings, and typography styles
• Inline styles cause specificity issues, since they trump separate stylesheets

Hope that helps!

Thanks,
Harry
