Oltre al colore è anche possibile variare la dimensione del rettangolo lampeggiante, inserendo a fine pagina prima della chiusura del tag </body> il seguente codice:

(in blu il codice da copiare): <a href="http://www.web-link.it/" target="_blank" onMouseOver="showlines(this,'red',4)" onMouseOut="hidelines()">http://www.web-link.it</a>
