html - CSS 导航栏内容缩放

Question

您好，我只是想知道缩放导航栏的最佳方式是什么，以便框的大小与屏幕宽度相关？

只是想让它有一点响应。谢谢

这是 CSS:

body {
  background-image: url("background2.jpg");
}
#navbar ul {
  padding: 5px;
  list-style-type: none;
  text-align: center;
  margin-left: 5%;
}
#navbar ul li {
  display: inline;
  float: left;
}
#navbar a:link {
  text-decoration: none;
  padding: 15px 162.5px;
  margin-left: auto;
  margin-right: auto;
  width: auto;
  color: white;
  background-color: #003333;
  font-size: 25px;
  font-family: Courier New;
}
#navbar ul li a:hover {
  color: black;
  background-color: #c2d6d6;
  text-decoration: line-through;
}
#navbar {
  background-color: #003333;
  width: 100%;
  height: 68px;
  border-radius: 15px;
}
a {
  display: block;
  width: 100px;
  background-color: #003333;
  transition-duration: 1s;
}
#navbar #currentpage a {
  color: black;
  text-decoration: line-through;
  background-color: #c2d6d6;
}
