任何人都可以帮助我让折叠式手风琴工作......不能使它工作，代码对我来说有一定道理并且它等于这个https://getbootstrap.com/docs/4.0/components/collapse/#accordion-example。
我有一个数据父级，即.card本身，ID =＆＃34;公司＆＃34;，每次折叠都针对此，每个按钮都针对其各自的可折叠内容 它是freecodecamp项目的。我已经制作了一些网页，但手风琴从不适合我，而不是用锤子打人。我认为向社区提问最好

<h2>Who is he? Well...</h2>
<blockquote>"If some of the things that Musk says and does sound absurd, that’s because on one level they very much are. On this occasion, for example, Musk’s assistant had just handed him some cookies-and-cream ice cream with sprinkles on top, and he then talked earnestly about <strong>saving humanity</strong> while a blotch of the dessert hung from his lower lip."</blockquote>
<p>Elon Reeve Musk (born June 28, 1971) is a South African-born American entrepreneur and businessman who founded X.com in 1999 (which later became PayPal), SpaceX in 2002 and Tesla Motors in 2003. Musk became a multimillionaire in his late 20s when he sold his start-up company, Zip2, to a division of Compaq Computers. </p>
