美好的一天！我正在尝试使用Font Awesome 5做一个固定的浮动动作按钮，当用户单击大按钮时，它将把Font Awesome转换或转换为另一个Font Awesome徽标。

这是您要实现的目标吗？悬停：

  display: flex;
  align-items: center;
  justify-content: center;
  position: fixed;
  right: 20px;
  bottom: 20px;
  transition: background-color 0.25s ease-out;
  border: none;
  cursor: pointer;
}

.floating-btn:hover {
  background-color: red;
}

.floating-btn i {
  transition: transform 0.25s cubic-bezier(.4,.2,1);

  transform: rotate(45deg);
