试图让我的导航栏按钮在屏幕处于选项卡或移动模式时工作

Question

所以我有我的导航栏和一个按钮，所以当屏幕缩小到一定尺寸时，导航栏变成带有三行的按钮，应该是一个下拉菜单，但它不起作用。我试图让它充当下拉菜单，然后我可以使用指向其他页面的链接来浏览此页面。该按钮在需要时显示，它是一个按钮，当鼠标悬停或单击时，它会变为灰色。但是单击它会向北移动。

我的 HTML 和 CSS:

.navbar {
  position: fixed;
  width: 100%;
  z-index: 999;
  padding: 30px 0;
  font-family: 'Ubuntu', sans-serif;
  transition: all 0.3s ease;
}

.navbar.sticky {
  padding: 15px 0;
  background: crimson;
}

.navbar .max-width {

Answer 1

使用一些 Javascript 很容易修复，正如您在这段代码中看到的，您现在可以在单击按钮时使其折叠和展开。

var navbar = document.getElementById("navbarNav");

function hideShow() {
  if (navbar.style.display == "block") {
    navbar.style.display = "none";
  } else {
    navbar.style.display = "block";
  }
}

/* navbar styling */

.navbar {
  position: fixed;
  width: 100%;
  z-index: 999;
  padding: 30px 0;
  font-family: 'Ubuntu', sans-serif;
  transition: all 0.3s ease;
}

.navbar.sticky {
  padding: 15px 0;
  background: crimson;
}

.navbar .max-width {
  display: flex;
  align-items: center;
  justify-content: space-between;
}

.navbar .logo a {
  color: #fff;
  font-size: 35px;
  font-weight: 600;
}

.navbar .logo a span {
  color: crimson;
  transition: all 0.3s ease;
}

.navbar.sticky .logo a span {
  color: #fff;
}

.navbar .menu li {
  list-style: none;
  display: inline-block;
}

.navbar .menu li a {
  display: block;
  color: #fff;
  font-size: 18px;
  font-weight: 500;
  margin-left: 25px;
  transition: color 0.3s ease;
}

.navbar .menu li a:hover {
  color: crimson;
}

.navbar.sticky .menu li a:hover {
  color: #fff;
}
