I’d change this:
class="' . esc_attr( $post->post_type ) . '-title entry-title"
and make a special class for this usage. For example, make it:
class="fb-list"
and then style it however you like in your style.css file:
.fb-list { font-size: 16px; font-weight: bold; }
I’d also change the <strong> tag to a <p> or <span> or something that’s more appropriate.
