To improve my customer experience, I wanted to have almost full width pages. So I followed an advise to add a new Layout to replace theme.liquid, and a new template to replace page.liquid. Instead of widh=600px max, I have now width=1000px max, and it works fine.
My problem is that, using this new template, H1, H2, H3.... doesn't works anymore when it was working on the previous page.liquid. How can I put back H1, H2, H3... on my new page template?
Example of impacted page: https://www.oneoffedition.com/pages/icons-glossary
Thanks in advance!
