before 元素的过渡效果

Question

我正在尝试让“预约”按钮在这个网站https://templates.hibootstrap.com/arrola/default/index-2.html上工作。 我有以下 css

.appointmentButton:before {
  content: '';
  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  transform: scale(0);
  left: 0;
  right: 0;
  opacity: 0;
  z-index: -1;
  transition: all 0.5s;
}

.appointmentButton {
  padding: 10px 30px;
  color: white;
  text-align: center;
  position: relative;
  overflow: hidden;
  z-index: 0;
  text-transform: capitalize;
  transition: 0.5s;
  background-color: $black1;
  border: none;
  outline: none;
  text-decoration: none;
  &:hover:before {
    background-color: $greenColor;
    transform: scale(1);
    opacity: 1;
  }
}

和 html 元素： <a className={styles.appointmentButton} href="/appointment">Book an Apppointment</a> 。 我试图让按钮背景颜色变为绿色。

appointmentButton 添加显示：内联块

 .appointmentButton { padding: 10px 30px; color: white; text-align: center; position: relative; z-index: 1; overflow: hidden; text-transform: capitalize; transition: 0.5s; border: none; outline: none; text-decoration: none; background-color: #191f30; display: inline-block; }.appointmentButton::before { content: ''; position: absolute; top: 0; left: 0; right: 0; width: 100%; height: 100%; transform: scale(0); opacity: 0; transition: all 0.5s; background-color: #72ae44; z-index: -1; }.appointmentButton:hover::before { width: 100%; height: 100%; transform: scale(1); opacity: 1; }

 <a class="appointmentButton" href="/appointment">Book an Apppointment</a>
