I am trying to override a CSS field to increase

Hi,

I am trying to override a CSS field to increase the font-size from 15px to 20px.

This is on the meet-our-family page of the website.
I can inspect the element and change the font-size to 20px. I cut and paste that CSS rule and add it to my custom css, but the override is not working.

.overlay_text > p {
font-size: 20px !important;
}

Any thoughts on what to do to get this working? Let me know if you need any other information from me.

Thanks for your help with this.
