导航栏没有变成汉堡包或没有响应

Question

我已经尝试自定义我的导航栏，我已经从 bootstrap 站点复制了 3.0 的基本导航栏。现在，我的导航没有变成汉堡导航，我用于导航杆的自定义背景图像，徽标杆，但导航按钮消失了。我假设它们会在背景图片下方或屏幕外变成汉堡。

.navbar {
  background: url(../images/mainnav.png) no-repeat top center;
  border-radius: 0;
  border: 0;
  height: 100px;
  width: 980px;
  margin: 0 auto;
  display: block;
}

.navspace {
  padding: 30px 46px 30px 46px;
}

.navposition {
  margin-left: 100px;
}

.navbar-brand {
  padding: 0;
  position: relative;
  left: 40px;
  top: 10px;
}

Answer 1

我遇到了同样的问题。我的解决方案是为 css:

中的图标栏设置背景色

.icon-bar {
    background-color: black;
}

Answer 2

你的 HTML 有很多问题。一些元素被注释掉，多余的结束标记如 </li> 或 </ul>，你的 html 中还有 max-width:100%。那里没有业务。

关于你的问题，问题是你设置了 .navbar { width:980px } 当然，当你在小于 980px 的屏幕上时，并不是所有的 .navbar 都可见（右边导航栏的一侧不适合屏幕）所以汉堡菜单在那里但不可见，因为 navbar 比屏幕大

如果您希望您的 .navbar 为 980px 但也具有响应能力（屏幕较小时缩放），请使用 max-width:980px

见下文

.navbar {
  background: url(../images/mainnav.png) no-repeat top center;
  border-radius: 0;
  border: 0;
  height: 100px;
  max-width: 980px;
  margin: 0 auto;
  display: block;
}

.navspace {
  padding: 30px 46px 30px 46px;
}

.navposition {
  margin-left: 100px;
}

.navbar-brand {
  padding: 0;
  position: relative;
  left: 40px;
  top: 10px;
}
