Wordpress title won't change size

Between the posts and pages on my website, the h1 size won't change:

-https://harrysnell.com/how-to-supercharge-your-motivation/

-https://harrysnell.com/emotional-eating-course/

I've added to the CSS - h1.entry-title {font-size: 100px;}

In the first link (post) it changes, but in the second (a page) it doesn't. It seems to be overridden somewhere and I can't work out where.

Any ideas what's going on?

 

As I understand both are different pages (I mean both pages are in different directories).
How to Supercharge Your Motivation is in harrysnell . com/blog and Emotional Eating Course is not in the same directory.

Add this as custom CSS for -https://harrysnell.com/emotional-eating-course/ and it will work

.ast-single-post .entry-title, .page-title {

1. font-size: 55px !important;
2. font-family: sans-serif !important;
3. font-weight: 700;

}

 

Thank you! Genius! It worked

 

Glad to know it worked for you.
