Thank you so much for your reply.
I tried copying tat CSS into several places but haven't had any luck unfortunately. My client is not liking the small, thin black settings boxes at all 🙁
I pasted the theme into the css box in the plugin; into my theme custom css; into the page I am trying to achieve the styling… and I haven't had luck.
I seem to be able to style the search box with the themes, however the settings boxes won't change at all.
One other thing. Can I increase the height of the Drop down column? In one column I have listed the days of the week however Sunday is being cut off and I need to scroll down to see it.
I look forward to your advice.
