Style sheet error

Hi Dan Hughes.

Thank you for contacting us and for using our theme. We appreciate it.

If I understood you correctly, it seems that you’re trying to edit the style.css file directly from the Editor?

If so, please don’t do that.
First, you might break something and second, any change you make that way will be overwritten when the theme gets updated. If you want to change something in the CSS, please use Appearance -> Customize -> Additional CSS section.

If there’s something else going on here, please let me know.

Kind regards.
