fonts settings in Bootstrap Studio

hello, I have built a site with BSS, it has numerous text used as headers, paragraphs etc. I want to globally change all H1 text to a font and paragraph to another font, will I have to click each font occurrence to set this or is there a faster way to do this?

Find the CSS that the tags are using and copy them to your custom CSS file. Now alter the fonts how you want them to be in those 2 CSS elements and that's it.
