正如你可以看到从上面的图片，我的电子邮件按钮边框显示灰色和白色时，边框颜色设置为显示白色边框。我已经张贴了下面的代码：

.email {
  margin: 18px 0 0 0;
  margin-bottom: 12px;
}
.email .emailText {
  border-radius: 35px;
  -ms-border-radius: 35px;
  -moz-border-radius: 35px;
  -o-border-radius: 35px;
  -webkit-border-radius: 35px;
  background-clip: padding-box;
  outline: none;
  -ms-outline: none;
  -moz-outline: none;
  -o-outline: none;
  -webkit-outline: none;
  background: rgba(0, 113, 188, 0.4);
  border-color: white;
  color: white;
  font-size: 1.6em;
  font-weight: 300;
  height: 58px;
  padding: 0 0 0 30px;
  width: 61.7021276596%;
  /* 580px/940px */
}
.email :-ms-input-placeholder {
  color: white;
}
.email ::-mox-placehold {
  color: white;
}
.email ::-webkit-input-placeholder {
  color: white;
}

<div class="email">
   <form action="#" class="emailBox" target="_blank" method="post">
  <input type="email" class="emailText" placeholder="enter email for early access" size="">
   </form>
</div>
