FX Elements is a Wordpress Plugin with an easy to use interface manager to add shortcodes to your website. FX Elements lets you customize content by adding animated elements as buttons, boxes, alert message, icons, etc. Each one of this elements has an smooth transition of color, opacity, size or position ( depending the shortcode ) between the initial status and the “mouse over status”.
