Wanting to display only thumbnail and title

So I’ve hacked the CSS to get what I want, sort of. ?? However I’d love to know a better solution.

body.archive .post-meta, body.archive .more-link, body.archive .post-comments, body.archive .post-info, body.archive p {
	display: none;
}

Well, I think I’ve figured out what code to use, just don’t know where to put it.

remove_action( 'genesis_before_post_content', 'genesis_post_info' );
remove_action( 'genesis_after_post_content', 'genesis_post_meta' );
remove_action('genesis_post_content', 'genesis_do_post_content');

You can use this:

.teaser .entry-content,
.teaser .post-info,
.teaser .post-meta {
	display: none;
	visibility: hidden;
}
