在我的html代码中，我有以下内容：
<section id="cta">

<!-- Footer -->
<footer id="footer">

</footer>
当页面加载时，我如何让我的部分占据整个屏幕，而页脚实际上下降到滚动条。请注意，这必须是动态的，因为不同的计算机具有不同的屏幕尺寸，我知道高度100％的技巧，但在我的情况下有多个元素，并且可以使特定的一个占据整个屏幕而另一个一个可以通过滚动访问？
谢谢！
我实际上尝试删除一个js脚本，它工作，所以我怀疑它在js脚本中定义了一些css，但我似乎无法找到哪个是冲突的CSS，我试图添加！重要的我当前的CSS，但它不会覆盖js脚本中的那个。
这是JS脚本：
