Customise Wordpress Twenty Twenty theme - remove author/date and the bottom navigation link (previous and next post)

wp2020customise.md

I only tested these on the Twenty Twenty theme.

To remove the author and date (below the post title)

.entry-categories-inner, 
.post-meta-single-top { 
  display: none;
}

    display: none;
}
