Center only a few pages in WordPress

First of all, I read how to access the CSS editor. I tried to open it to try to center the title only. Here is the page I was trying to the title on: https://www.english-dubbed.com/reviews-and-other-stuff/voice-actors-spotlight/featured-voice-actors/alexis-tipton/. How can I do this for just one page? I need simple instructions as I have never worked with CSS before.
