I guess I am being a pain at the moment, but developing the mobile version website I need to make the carousel text size bigger.
Etienne C posted a response to the same queston back in 2015 as follows:
"If you want the CSS for the carousel text to impact all carousels in your site, you can add the CSS above to the end of style.css which can be accessed from the CSS Code tab of Style View."
.jcarousel-skin-nof .jcarousel-caption {
font-size: 1.25em;
font-family: 'Comic Sans MS', cursive;
padding: 14px;
}
However, looking in CSS Styles I cannot see this parameter and cannot insert it.
