今天我学会了如何创建常见问题解答折叠功能
好了，现在我们要设置这些按钮（图标按钮）的样式，并定位它们。
我们希望赋予它们功能，以便我们可以扩展和收缩这些虚假提示。
所以我们在按钮上设置了一个伪提示破折号切换功能。
显然，我们不想在雪佛龙图标展开时显示它，也不想在……时显示 X。
如果它没有被扩展的话。
所以我们必须解决这个问题。
但我们先来做一些基本的事情。
比如，我要把背景颜色设为透明，并去掉边框。

这是我的 JavaScript 代码
const toggles = document.querySelectorAll(".faq-toggle");
toggles.forEach((toggle) => {
toggle.addEventListener("click", () => {
toggle.parentNode.classList.toggle("active");
});
});
以下是输出结果
