How to chaneg Page Title font size

Hi,

3.9.2.

I can see where to change Headings etc in Pages but can’t see where to chnage the size of the Page Title Font size.

I want it just a little smaller.

I see in another past pots to change it in the stylesheet.css.

I looked there and there are a few places where page title is mentioned.

I see this on row 3137 Is this it?

.page-title,
.entry-title {
font-size: 21pt;
}

Thanks
