H1 and H2 headlines – want to change

Hi support! :) Your theme is perfect but from a SEO viewpoint one change might improve it. Now the main header of the page is: <h1 class="site-title"> And the header for page och post: <h2 class="entry-title"> It would be better to instead have it: The main header of the page: <class="site-title"> And the header for page och post: <h1 class="entry-title"> 1. Is it possible for you to update the theme in the future to this? 2. Can you please provide me a code for the CSS or a childtheme to change this on my site? Thanks a lot in advance!
