我尝试了很多变体，从未让 CSS 100% 正确。

.navButton {
    width:15%;
    display:inline-block;
    position:relative;
    background-color:#03314b;
    border-radius: 30%;
    box-shadow: 2px 2px 2px #888888;
}
 .navButton:hover {
    background-color:#98b7c8;
}
.navButton span {
    width:100%;
    display:inline-block;
    position:absolute;
    border-radius: 30%;
    box-shadow: 2px 2px 2px #888888;
}
.navButton .bg {
    height:50%;
    top:0;
    background-color:#3a6076 ;
    border-radius: 30%;
    box-shadow: 2px 2px 2px #888888;
}
.navButton:hover .bg{
    background-color:#afcad9;

}
.navButton .text {
    position:relative;
    text-align:center;
    color:#fff;
    vertical-align: middle;
    align-items: center;
}
.navButton .text:hover {
    color:#000000;
}

<a href="contact.html" class="navButton">
    <span class="bg"></span>
    <span class="text">Contact</span>

Answer 1

一个非常相似的，使用 linear-gradient 和更少的 HTML 标记

jsFiddle

.navButton {
  color: white;
  text-decoration: none;
  font-family: Helvetica, Arial, sans-serif;
  font-size: 14px;
  text-align: center;
  padding: 0 30px;
  line-height: 30px;
  display: inline-block;
  position: relative;
  border-radius: 20px;
  background-image: linear-gradient(#335b71 45%, #03324c 55%);
  box-shadow: 0 2px 2px #888888;
  transition: color 0.3s, background-image 0.5s, ease-in-out;
}
.navButton:hover {
  background-image: linear-gradient(#b1ccda 49%, #96b4c5 51%);
  color: #03324c;
}

<a href="contact.html" class="navButton">Contact</a>
