我如何让我的购物车-btn开始工作？

Question

在导航栏中，我有一个购物车按钮，单击它时应该打开它，单击关闭按钮时应该关闭它。由于某种原因，它不起作用。

我在 CSS 样式中创建了一个

.active

类，并使用

querySelector()

来获取

#cart-btn

id 和

.close

类。我尝试在单击

cart-item-container

时添加

cart-btn

类，并在单击关闭按钮时删除它

let shoppingcart = document.querySelector('.cart-items-container');

document.querySelector('#cart-btn').onclick = () => {
  shoppingcart.classList.add('active');
}

document.querySelector('.close').onclick = () => {
  shoppingcart.classList.remove('active');
}

header .icons #cart-btn {
  position: relative;
  z-index: 1;
  display: flex;
  align-items: center;
  justify-content: center;
  left: 70px;
}

header .icons #cart-btn .totalQuantity {
  position: absolute;
  top: -5px;
  right: 15px;
  font-size: 10px;
  background-color: #b31010;
  width: 15px;
  height: 15px;
  border-radius: 50%;
  color: var(--white);
  font-weight: bold;
  display: flex;
  justify-content: center;
  align-items: center;
  transform: translateX(20px);
}

header .cart-items-container {
  color: var(--light-black);
  position: fixed;
  top: 0;
  right: -100%;
  width: 400px;
  height: 100vh;
  background: var(--white);
  display: flex;
  flex-direction: column;
  padding: 25px;
  box-sizing: border-box;
  transition: right 1s;
}

header .cart-items-container .active {
  right: 0;
}

<div class="icons">
  <div class="iconCart">
    <div id="cart-btn" class='bx bx-shopping-bag'>
      <div class="totalQuantity">0</div>
    </div>
  </div>
  <div id="account-btn" class='bx bx-user'></div>
  <div id="menu-btn" class='bx bx-menu'></div>
</div>

<!--SHOPPING CART-->
<div class="cart-items-container">
  <!--div id="close" class='bx bx-x'></div-->
  <h2>CART</h2>
  <div class="listCart">
    <div class="item">
      <img src="images/shop-3.png" alt="">
      <div class="content">
        <div class="name">
          Product Name
        </div>
        <div class="price">
          $50/1 product
        </div>
      </div>
      <div class="quantity">
        <button>-</button>
        <span class="value">3</span>
        <button>+</button>
      </div>
    </div>
  </div>
  <div class="buttons">
    <div class="close">CLOSE</div>
    <div class="checkout">
      <a href="checkout.html">CHECKOUT</a>
    </div>
  </div>

</div>
