Change h1 font size on all product pages in Palo Alto

Store Design

Topic summary

Goal: set the h1 (top-level heading) font size to 175% across all product pages in the Palo Alto theme without editing each product template individually.

Current approach: using CSS (h1 { font-size: 175%; }) but applied manually on each product template, which is inefficient.

Latest update: a helper requested the store URL and password to review the theme setup and provide an exact, theme-specific solution.

Status: unresolved and ongoing. Action item: share store access details. Open question: how to implement a global CSS change for product pages without per-page edits.

Hi,

I want to change the h1 font size on all product pages to 175%.

To do this, I now have the follwoing CSS, but I need to manually set that up on every single product template:

h1 {
font-size: 175%;
}

Is there a way to set this as the default for all product pages wihtout doing CSS in every product page section?

Thanks.
