testimonial custom css

I put the following code (provided by you) in the custom.css file and in Theme General Styling. It worked for one of my sites. I have two, using the same theme for both. Can you take a look why the changes are not working on this particular site? The goal is to reverse the sizes of the text in the testimonial carousel. Where the name is larger and the quote is smaller. I’ll put login info in private section.

strong.avia-testimonial-name {
font-size: 7px !important;
}
.avia-testimonial-content {
font-size: 10px !important;
}
#top .av-large-testimonial-slider .avia-testimonial-meta {
margin-top: 7px;
}
