enter image description hereenter image description here我使用 html css 和 javascript 创建了一个网页。在主页中，我添加了一个弹出式联系按钮和表单，它正在工作，但在页面顶部打开了弹出窗口。主页就像您滚动的一页。我将按钮添加到页脚，但表单在页眉附近打开。我希望它在用户看到页面末尾时打开。我希望我能解决问题。
https://github.com/ipeksaygut/website 在此链接中只有主页的 HTML-CSS-JS 文件。
我真的是初学者，我真的不明白这个问题。感谢帮助！
-如果有什么需要让我知道以解决问题！ 窗口被视为图片，但我想在页面末尾看到它

嗨 Ipek Saygut！
我把这段代码放在一起，让你了解你的 css 发生了什么。我修改了 .popUp 类以解决这个问题。请注意，您需要阅读有关 HTML 和 CSS 最佳实践的更多信息。请阅读这篇文章，让您在 HTML 和 CSS 的奇妙世界中入门，别担心，这需要练习，但您很快就会掌握它。 HTML & CSS Best Practices.
我当然希望这段代码有帮助，玩得开心，伙计！
let btn = document.querySelector("button");
let cont = document.querySelector(".popUp");
btn.addEventListener('click', function(){
cont.id = "show";
});
cont.addEventListener('click', function(e){
if(e.target == this){
this.id = "hidden";}
e.preventDefault;
