Here's how you solve the problem:
In file /components/com_jcomments/tpl/default/style.css:
section /*comment*/
row:
#comments {margin: 0;padding: 0;width: 100%;text-align: left;text-decoration: none;text-transform: none;text-indent: 0;}
replace with:
#comments {margin: 0;padding:4px 10px;margin-left:3px;text-align: left;text-decoration: none;text-transform: none;text-indent: 0;}
for mi its work
