How do I edit a subclass of "top-parallax-section"

I am trying to edit the code within my website but am having some trouble editing the code so that I can change only the style within that section. Would I go into the theme editor and change the name of this one?

The code that I put down for the original top parrallex section is

body.home .top-parallax-section * {
color: black;
font-weight: bolder;
padding-top: px;

I would like to make the text not appear so big, and turn that specific sections font white instead of black. (The one that is titled’ Tsunami in your pipes’)

any help would be much appreciated, have a good morning!

Good morning to you :slight_smile:
