这是一种方法，就像它在网站上所做的那样：

CSS：

button {
    text-rendering: auto;
    color: initial;
    letter-spacing: normal;
    word-spacing: normal;
    text-transform: none;
    text-indent: 0px;
    text-shadow: none;
    display: inline-block;
    text-align: start;
    margin: 0em 0em 0em 0em;
    font: 13.3333px Arial;
}
user agent stylesheetinput,
textarea,
keygen,
select,
button,
meter,
progress {
    -webkit-writing-mode: horizontal-tb;
}
user agent stylesheetbutton {
    -webkit-appearance: button;
}
.btTxt submit {
    border: 3px solid #fff;
    color: #fff;
}
.btTxt submit {
    border: none;
    font-family: inherit;
    font-size: inherit;
    color: inherit;
    background: none;
    cursor: pointer;
    padding: 25px 80px;
    display: inline-block;
    margin: 15px 30px;
    text-transform: uppercase;
    letter-spacing: 1px;
    font-weight: 700;
    outline: none;
    position: relative;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    transition: all 0.3s;
}
*,
*:after,
*:before {
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}

希望这有帮助！有一个快乐的圣诞节： - ）

有很多方法可以做到这一点。这个CSS可以帮到你。

#button {

  /*Reset*/
  display: inline-block;
  outline: none;
  background-color: transparent;

  /*Some fancy stuff*/
  padding: 0 20px;
  line-height: 200%;
  border: 1px solid silver;

  /*Magic*/
  background-image: linear-gradient(PaleVioletRed, PaleVioletRed 50%, Sienna 50%, Sienna);
  background-size: 100% 200%;
  -webkit-transition: background-position .3s;
  transition: background-position .3s;
}
#button:hover {
  background-position: 0 -100%;
}
