Change h3 in Header to h1

I am currently working with this theme and I was wondering how I can change the “Blog Name in Top Callout - Heading for the Blog page” which you can find under Blog Settings > Blog Index Settings from the default <h3> to <h1>. I know I can change the font-size via css but this is not what I want to archive.

Would be really happy if someone can help me with this.

Best Regards

Hello there,

I hope you are doing well today.

You could change the H tags by going to Appearance > Editor and locate the blog template then change it there or you can change the appearance of the header using CSS.

Best Regards,
