CSS Overrides for a Community Polls

Hello.
I use Community Polls 3.4.x and would like to use standard Joomla template overrides.

Now I added modified styles to my joomla-template css file. But I don't want to load them in non CP page.

So, to use Overrides I need to createtemplates/my_template/html/com_communitypolls/... what else?ortemplates/ja_elastica/html/com_cjlib/bootstrap/css/cj.bootstrap.min.css?

Is far is I understand, I need to create empty file and paste:
@import url("../../../../../components/com_communitypolls/*********.css");
/* Add overrides bellow */ and add only modified styles?
Thanks.
