}  @keyframes gradient {  0% {  background-position: 0% 50%;  }  50% {  background-position: 100% 50%;  }  100% {  background-position: 0% 50%;  }  
}  .form-container button:active {  scale: 0.95;  
}  .form-container .form {  display: flex;  flex-direction: column;  gap: 20px;  
}  .form-container .form-group {  display: flex;  flex-direction: column;  gap: 2px;  
}  .form-container .form-group label {  display: block;  margin-bottom: 5px;  color: #717171;  font-weight: 600;  font-size: 12px;  
}  .form-container .form-group input {  padding: 12px 16px;  border-radius: 8px;  color: #fff;  font-family: inherit;  background-color: transparent;  border: 1px solid #414141;  
}  .form-container .form-group textarea {  padding: 12px 16px;  border-radius: 8px;  resize: none;  color: #fff;  height: 96px;  border: 1px solid #414141;  background-color: transparent;  font-family: inherit;  
}  .form-container .form-group input::placeholder {  opacity: 0.5;  
}  .form-container .form-group input:focus {  outline: none;  border-color: #e81cff;  
}  .form-container .form-group textarea:focus {  outline: none;  border-color: #e81cff;  
}  .form-container .form-submit-btn {  display: flex;  align-items: flex-start;  justify-content: center;  align-self: flex-start;  font-family: inherit;  color: #717171;  font-weight: 600;  width: 40%;  background: #313131;  border: 1px solid #414141;  padding: 12px 16px;  font-size: inherit;  gap: 8px;  margin-top: 8px;  cursor: pointer;  border-radius: 6px;  
}  .form-container .form-submit-btn:hover {  background-color: #fff;  border-color: #fff;  
}

🌟 关键技术点如下：

CSS动画：使用了@keyframes规则创建了一个名为gradient的动画，该动画会改变背景的位置，从而实现背景渐变的动态效果。
CSS Flexbox：使用了Flexbox布局来排列.form-container元素的内容。这包括主轴和交叉轴的对齐、方向和间距。
CSS过渡：在.form-container .form-submit-btn:hover选择器中使用了过渡效果，使得背景颜色和边框颜色的变化更加平滑。
CSS伪类：使用了:active、:focus和:hover伪类来改变按钮和输入框在不同状态下的样式
