With regards to the More tag; That is a core feature of WordPress that is only intended for you to specify where the excerpt should end on blog posts. It is not a general element that can be used on pages to show/hide content. Attempting to insert it into a page, or anywhere outside of a blog post will be ignored - you can verify the same thing will occur when switching to the default WP theme.

How can I add a view more / view less button in a block text or responsive text?
Can I just add a section for it? Should I add any html or Css code?
Thanks,
