You need to edit the slim-plus.css file found here:
../wp-content/plugins/slim-plus

Change the value here:

#cn-slim-plus .cn-entry {
	clear: both;
	font-size: 12px !important;
	position: relative;
}

Make a new minified version named slim-plus.min.css and overwrite the original version.

after you do that, make sure to force refresh to browser to see the changes.
