我的问题是按钮显示得非常小，而且我在下面调整高度或宽度没有任何效果。

我已经将代码输入到我的WordPress网站中使用Elementor，我只是拖动了一个HTML小部件并粘贴了下面的代码。

.container {
  height: 100vh;
  width: 100vw;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: white;
}
.btn {
  padding: 20px 60px;
  border: none;
  outline: none;
  position: relative;
  z-index: 1;
  border-radius: 5px;
  background: linear-gradient(to right, #00FFA3, #DC1FFF);
  cursor: pointer;
}
.btn::before {
  content: "";
  position: absolute;
  left: 1px;
  right: 1px;
  top: 1px;
  bottom: 1px;
  border-radius: 4px;
  background-color: white;
  z-index: -1;
  transition: 200ms
}
.btn::after {
  content: attr(data);
  font-size: 16px;
  background: linear-gradient(to left, #00FFA3, #DC1FFF);
  -webkit-background-clip: text;
  color: transparent;
  transition: 200ms
}
.btn:hover::before {
  opacity: 50%;
  top: 0px;
  right: 0px;
  bottom: 0px;
  left: 0px;
}
.btn:hover::after{
  color: white;
}






body .container {
  height: 10vh;
  width: 20vw;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: white;
}

body .btn {
  padding: 20px 60px;
  border: none;
  outline: none;
  position: relative;
  z-index: 1;
  border-radius: 5px;
  background: linear-gradient(to right, #00FFA3, #DC1FFF);
  cursor: pointer;
}

body .btn::before {
  content: "";
  position: absolute;
  left: 1px;
  right: 1px;
  top: 1px;
  bottom: 1px;
  border-radius: 4px;
  background-color: white;
  z-index: -1;
  transition: 200ms;
}

body .btn::after {
  content: attr(data);
  font-size: 16px;
  background: linear-gradient(to left, #00FFA3, #DC1FFF);
  -webkit-background-clip: text;
  color: transparent;
  transition: 200ms;
}

body .btn:hover::before {
  opacity: 50%;
  top: 0px;
  right: 0px;
  bottom: 0px;
  left: 0px;
}

body .btn:hover::after {
  color: white;
}

<div class="container">
  <button class="btn" data="点击我"></button>
</div>
