您好我会问我怎样才能在带有箭头的矩形中添加边框。我的代码是:
a.trapez_sharp::after {
content: "";
border-top: 22px solid transparent;
border-bottom: 22px solid transparent;
border-left: 20px solid #ED1D24!important;
position: absolute;
right: -20px;
top: 0;
}
a.trapez_sharp {
display: block;
float: left;
height: 44px;
background: #ED1D24;
text-align: center;
padding: 0px 6px 0 8px;
position: relative;
margin: 0px 29px 0 17px;
font-size: 20px;
text-decoration: none;
color: #fff;
}
a.trapez_sharp::before {
content: "";
border-top: 22px solid transparent;
border-bottom: 22px solid transparent;
border-right: 25px solid #ED1D24;
position: absolute;
top: 0;
left: -25px;
}

<a class="trapez_sharp" href="www.google.gr">See our services -></a>

我想添加一条显示形状的边框线。我可以在a.trapez_sharp上添加边框:1px solid #ffffff; ,但是当我把它添加到之后和它被破坏之前。 任何建议都会有所帮助
