Proper loading of styles

Hey Michelle,

using your plugin with WP_DEBUG on true throws some general error messages due to the implemented call on the enqueued styles. You should wrap the following lines in a function and hook it into an action.

wp_register_style('htprfb_like_box_css', HTPRFB_PLUGIN_PATH . 'style.
wp_enqueue_style('
wp_register_style('htprfb_fontawesome', '//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.4.0/css/font-awesome.min.
wp_enqueue_style('htprfb_fontawesome');

For example hook it into ‘wp_enqueue_scripts’ as Codex suggests or how I prefer into ‘wp_head’:

add_action( 'wp_head', 'htprfb_load_styles' );
/**
 * Action hook to load Plugin specific Stylesheets.
 *
 * @since 1.2.2
 *
 * @uses HTPRFB_PLUGIN_PATH
 *
 */
function htprfb_load_styles(){

	wp_register_style('htprfb_like_box_css', HTPRFB_PLUGIN_PATH . 'style.css');
	wp_enqueue_style('htprfb_like_box_css');
	wp_register_style('htprfb_fontawesome', '//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.4.0/css/font-awesome.min.css');
	wp_enqueue_style('htprfb_fontawesome');
}
