Photo caption - change background color

Page in question here

Is it possible to make the photo caption background the same grey as the surrounding box?

Hello there,

Thank you for asking. Sure, it’s possible. What you need to do is to add the below CSS code into Appearance > Customize > Additional CSS in your site dashboard.

.timeline .wp-caption {
  background: transparent;
  border: none;
