在回應式頁腳選單中添加“固定”div-有解無憂

在以下 w3schools 代碼中，我在網頁底部實作了回應式選單，我添加了一個帶有域著作權宣告的 div。我想讓著作權 div在螢屏底部居中，只要它沒有被選單項覆寫，因為瀏覽器視窗變小，然后在頁面底部再次移動選單項下方的選單項被它們覆寫，或者當選單在之前最小化時被相關按鈕打開時。

function myFunction() {
  var x = document.getElementById("myNavbar");
  if (x.className === "navbar") {
    x.className  = " responsive";
  } else {
    x.className = "navbar";
  }
}

body {
  margin: 0;
  font-family: Arial, Helvetica, sans-serif;
}

.navbar {
  overflow: hidden;
  background-color: #333;
  position: fixed;
  bottom: 0;
  width: 100%;
}

.navbar a {
  float: right;
  display: block;
  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

.navbar a:hover {
  background-color: #ddd;
  color: black;
}

.navbar a.active {
  background-color: #04AA6D;
  color: white;
}

.navbar .icon {
  display: none;
}

#copyright {
  position: absolute;
  top: 20%;
  left: 25%;
  width: 50%;
  height: 50%;
  color: white;
}

@media screen and (max-width: 600px) {
  .navbar a:not(:first-child) {
    display: none;
  }
  .navbar a.icon {
    float: right;
    display: block;
  }
}

@media screen and (max-width: 600px) {
  .navbar.responsive .icon {
    position: absolute;
    right: 0;
    bottom: 0;
  }
  .navbar.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
}

歡迎任何有關良好實施的想法！

試試這個解決方案：

function myFunction() {
  var x = document.getElementById("myNavbar");
  if (x.className === "navbar") {
    x.className  = " responsive";
  } else {
    x.className = "navbar";
  }
}

body {
  margin: 0;
  font-family: Arial, Helvetica, sans-serif;
}

.navbar {
  overflow: hidden;
  background-color: #333;
  position: fixed;
  display: flex;
  justify-content: center;
  bottom: 0;
  width: 100%;
}

.navbar a {

  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
