Center med WAP?

Hej
Hvordan kan jeg lave så det her står center?

Min kode:

<?xml version="1.0"?>
    <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
    "http://www.wapforum.org/DTD/wml_1.1.xml">
    <wml>
      <card id = "index" title = "3510i">
          <p>
            <img src="scooter.jpg"/>
            <anchor>Download<go href="scooter.jpg"/></anchor>
          </p>
      </card>
    </wml>
