To use CSS to target all H1, H2, H3 tags on a specific page, you can follow these.

#1. First, find Page ID.

In my example, we will have: #collection-66c7d2c899f0bb783dacb579

#2. Next, use CSS code like this to Custom CSS box.

#collection-66c7d2c899f0bb783dacb579 {
  h1 {
    font-size: 30px !important;
  }
   h2 {
    font-size: 40px !important;
  }
   h3 {
    font-size: 10px !important;
  }
}
