Well first of all, put gradient on edges is a bit difficult,
EDITED:
made this small example of a button the result is almost identical:
a {
text-decoration: none;
font-family:sans-serif;
}
input{
background:none;
border: none;
}
.outer {
padding: 2px;
text-align: center;
border-radius: 8px;
background: linear-gradient(to right, #04a6f3, #0072ff);
width: 150px;
}
.inner {
display: block;
border-radius: 6px;
font-size: 18px;
font-weight: 700;
width: 100%;
background-color: #fff;
color: #0095ff;
height: 100%;
padding-top: 10px;
padding-bottom: 10px;
}
<div class="outer">
<a href="#" class="inner">CONHEÇA</a>
</div>
