To add or override CSS: use the “Additional CSS” option in the customizer. https://codex.www.ads-software.com/CSS#Custom_CSS_in_WordPress

Learn to use the Chrome Developer Tools to help you see and test changes to your CSS.

THANK YOU!

That works perfectly.

Another related question…

Although the navigation arrows and stop/start button are light grey, they interfere with the image clarity.

Any way to get rid of them?

If it’s a matter of Additional CSS, how would I add it to your earlier solution for the white background and border.

Again, thanks for your help.
