The problem is that the media/text block from WordPress uses the <p>
tag for text so it inherits the body font.
Can I make a recommendation to create that layout without using the media text block?
Since you are already using a grid block from GB, you can just add an image block on the left and use the headings block on the right to create the exact same layout then you can use <h2>
or <h3>
from the headings blocks so it would inherit the right setting from the customizer.
That would be the best solution for sure π
