  </div>

</nav>

当我减少谷歌浏览器的大小时，类别和其他内容会重叠width:1502px处的徽标 我试过这个css 

@media (max-width:1502px){
  .navbar-brand {
    height: 80px; 
  }
  .navbar {
    background-color: #ccc; 
  }
  .navbar-toggle {
    margin-top: 25px; 
  }
}

也许这就是你要找的东西：

.navbar-brand {
    padding: 0px !important;
}

    .navbar-brand > img {
        height: 100%;
        width: auto;
    }

@media (min-width:768px) {
    .navbar-brand {
        padding: 15px 0px 0px 0px !important;
    }
}

因为你的导航内部有很多链接，并且由于字体大小的增加，它会溢出，因为空间不足，视口越小。

您可以更改导航栏折叠的断点，另外您可以更改链接的显示属性以便它们换行。这将使他们暴露更长时间，但你仍然需要在正常之前折叠导航。
