Help Please: Installing Web Fonts And File To Edit For H1

I want to add webfonts, I gather from one post these would be added the schema.json file under Font Families - Is this correct.

If the above is correct in which file would I alter the H1 style to change the style to the new webfont?

Thanks in advance.


You can add new font via the CSS section of the Theme editor

Then add the following query there

h1 {
    font-family: 'MyWebFont' !important;
