Comments box

A complete newbie here. I some how have two comment boxes one above and one below the post. I would like to remove the one above and keep the date Also the comment box does not respond as expected after leaving a comment i would assume it should close and go back to the post? whatiwant.xyz below is the custom css already in use I would prefer not too loose these customizations */ .by-author { display: none; } .cat-links, .tag-links, .sep { display: none; }
