.btn{

padding-top:3px;
border-top: 1px solid #44b549;
border-right: 1px solid #44b549;
border-bottom: 1px solid #44b549;
border-left: 1px solid #44b549;
width:100px;
height:30pt;
font-size:15pt;
border-radius：3em;
background-image: linear-gradient(to bottom, #44b549 0px, #44b549 100%);

} 注意一定不能少了这一段，此段定义打开页面时按钮的初始样式。若没有这段，页面打开时按钮不显示样式，直至有鼠标悬停。
