【问题描述】：
我想达到一个简单的效果，但是做错了什么。
基本上，我想使用 JQuery animate() 函数将表单从右侧滑到屏幕上，同时将不透明度从 0 调到 1。
我有一个 CLASS 为 "contact__formContainer" 的 DIV 元素，在其中我有一个非常简单的表单，其 CLASS 为 "contact__form"。
我对一些 CSS 进行了 SASS 编译，以便 contact__formContainer 将初始不透明度设置为 0，并将 margin-left 属性设置为 150vw。在我的 Javascript 中，我初始化了一个 const 变量 "formContainer" 并使用 animate() 函数来尝试减少 left-margin 属性的值。
我搜索的所有示例似乎都将left-margin属性写为leftMargin，这让我有点困惑。这是我第一次使用 SASS，但我认为这不是问题。
以下是相关的 HTML、SASS 和 Javascript。感谢您花时间帮助我。如果结果是我忽略了一些简单的事情，我会花更多的时间来发布问题......只是被难住和沮丧。再次感谢！
