1) How can change the page title layout in blogs only? I want to display that blog head image only not any info like data author category etc(refer to ss 1)
2) How can I create a widget with the current category and post-publish date? (refer to ss 2)
3) Can I put different fonts for blog posts only not woocommerce and others?
2. Sorry but there is no option in Theme Settings available for that. It requires customization and this is out of our theme support scope.
3. The font can be changed through the page builder, or rather edit any post and in the Text block settings -> Style -> Custom typography -> set any font as you want (more detail in the below video).
