input如何在各个浏览器下保持UI统一？

.ibutton { padding: 3px 15px; *padding: 0 15px; *height: 24px; font-size: 12px; text-align: center; text-shadow: #CF510B 0 1px 0; border:1px solid #ec5c0d; border-radius: 2px; background: #FC750A; background-image: -webkit-linear-gradient(top, #fc8746, #ec5d0e); color:#FFF; cursor: pointer; display: inline-block; }
