How do I change the font size of the picture title?

The titles to the albums and pictures are really big. I would like to change the size of the font.

I tried this code:

How do I change the font size of the picture title:

.media #item-body .bp-media-gallery h4 { font-size: 10px; }

But with no luck

The area where all the pictures are is private so I can’t send a link. But below is what is showing for one of the pictures.

				<div class="rtmedia-item-title">
			<h4 title="Cast">
				Cast				</h4>


Hello @tammy1999,

Please once try using below class hierarchie:

.rtmedia-container .rtmedia-list .rtmedia-item-title h4 {
  font-size: 10px;

I hope this will help you.

Thank you.

Thanks for the reply, but it didn’t help.

Hello @tammy1999,

Could you please once try the above code with any default theme of WordPress?

Let us know if the issue still remains.

Thank you.

Tried in Twenty Sixteen and it didn’t change the font size at all. I tried different sizes

Hello @tammy1999,

We are not able to regenerate the issue at our end.

Could you please provide your site URL where we can visit any public gallery? It will help us to debug the cause.

Thank you.

There isn’t a public page with the gallery. I can give you a username and password to get into that area but will need to do that privately
