我想在按钮前面做一个襟翼……有什么想法吗?
.button {
position:absolute;
top:240px;
left: 452.5px;
width:110px;
height:40px;
display: block;
margin-bottom: 10px;
text-align: center;
line-height: 30px;
margin: 20px;
cursor: pointer;
color: #fff;
text-align: center;
border: solid #009c93 1px;
border-top-right-radius: 7px;
border-bottom-right-radius: 7px;
background: #009c93;
text-shadow: 2px 2px #222222);
}
