I guess this is a novice question but here it is.
I have been editing a child theme CSS and trying to change this specific code
@media (min-width: 769px)
#carousel-hestia-generic span.sub-title {
font-size: 24px;
}
Which I see from the inspect in Chrome. When I add it to my style.css in my child theme and make the font size let's say 36px, it doesn't change. Actually, Chrome shows a strikethrough...
