我想在页脚中创建“按钮”。单击这些按钮将以 Accordion 式样式显示内容。我已经生成了我认为完美的代码，它可以工作，但是，当我单击一个按钮时，所有按钮都会随着内容向上移动。我只希望其中一个向上移动，其余的则锁定在页脚上。此外，可能在窗口内居中(目前它粘在左边)
如有任何帮助，我们将不胜感激。
我添加了一张图片来展示我想要的: enter image description here
现在代码如下:

在 .row 上使用 flexbox 并对齐结束
.row {
display: flex;
align-items: flex-end;
justify-content:center;
}
var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].addEventListener("click", function() {
this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.maxHeight) {
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight + "px";
}
});
