I’m trying to customize a theme but am having difficulty pin-pointing an element in Theme Editor that I wish to change.
Specifically, it’s the ‘read mail’ form and I want to change the color of the header (delineated with red border in the attachment) to light grey to visually distinguish it from the white background of the e-mail body.
Thanks for any assistance. If I should look elsewhere for this, please let me know.
Thanks/Regards, ..
