CSS -悬停时100%的宽度，尽管将元素设置为不同的宽度

我对CSS有问题。我把所有的都放在中心，它工作正常，但有一个问题与悬停css。当我设置active class或hover li元素时，背景颜色被设置为100%。此外，parapraph从左侧开始，并不完全在元素之下。我试着检查代码，但没有看到任何东西。
原因是什么？以后如何避免类似的事情发生？？

我想得到这样的东西：

我试着预览代码和改变宽度和其他类

function myFunction() {
  var input, filter, ul, li, a, i, txtValue;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  ul = document.getElementById("myUL");
  li = ul.getElementsByTagName("li");
  for (i = 0; i < li.length; i++) {
    a = li[i].getElementsByTagName("a")[0];
    txtValue = a.textContent || a.innerText;
    if (txtValue.toUpperCase().indexOf(filter) > -1) {
      li[i].style.display = "";
    } else {
      li[i].style.display = "none";
    }
  }
}

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.display === "block") {
      panel.style.display = "none";
    } else {
      panel.style.display = "block";
    }
  });
}

我设法修复了你的一些代码。问题是，活动色调来自背景，而不是边界，这是CSS中常见的事情。
不是这个星球上最干净的代码，有很多需要简化的地方，但是嘿，我想你可能会喜欢它！

你可以改变你。面板类这样

.panel {
   padding: 0 18px;
   margin: 0 auto;
   width: 90%;
   display: none;
   background-color: white;
   color: var(--main-color);
   overflow: hidden;
}
function myFunction() {
  var input, filter, ul, li, a, i, txtValue;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  ul = document.getElementById("myUL");
  li = ul.getElementsByTagName("li");
  for (i = 0; i < li.length; i++) {
    a = li[i].getElementsByTagName("a")[0];
    txtValue = a.textContent || a.innerText;
    if (txtValue.toUpperCase().indexOf(filter) > -1) {
      li[i].style.display = "";
    } else {
      li[i].style.display = "none";
    }
  }
}

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.display === "block") {
