Collapsible Date/Author/Comments/Ratings

Hello all

I have a blog where I post my poems, and as such I only want the Title and Poem (Post body) to be displayed (to make reading simpler), and have a “More” link in the bottom of each post that when clicked will expand into Date/Author/Comments/Ratings, which are already ligned up. the blog is https://pangrama.com .

Anyone knows how to do this?

thanks
