Pour mon "bouton" avec Firebug j'ai ça, mais je ne trouve pas comment déplacer le bouton envoyer:
élément {
}
.button, button, p.readmore a, #header input.button, .pagenav a:link, .pagenav a:visited, #advanced-search-toggle,
.profile-edit a:link, .profile-edit a:visited, h3.js_heading {
background-color: #ddd;
background-repeat: repeat-x;
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr="#ffffff", endColorstr="#dddddd");
background-image: -khtml-gradient(linear, left top, left bottom, from(#ffffff), to(#dddddd));
background-image: -moz-linear-gradient(top, #ffffff, #dddddd);
background-image: -ms-linear-gradient(top, #ffffff, #dddddd);
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #ffffff), color-stop(100%, #dddddd));
background-image: -webkit-linear-gradient(top, #ffffff, #dddddd);
background-image: -o-linear-gradient(top, #ffffff, #dddddd);
background-image: linear-gradient(#ffffff, #dddddd);
border-color: #b2b2b2 #b2b2b2 hsl(114, 0%, 62.5%);
text-shadow: 0 1px 1px rgba(255, 255, 255, 0.49);

}
.button, button, .profile-edit a {
