只需使用媒体查询，您的导航将生成默认的移动导航。

/* Navbar */

.navbar .logo:hover {
  background: none;
}
.navbar .nav > li > a:hover {
  background: none;
}
.navbar .navbar-toggle {
  background: white;
  border: thin solid gray;
}
.navbar .icon-bar {
  background: gray;
}
@media (min-width: 768px) {
  .navbar .middle-left {
    margin-left: 25%;
  }
  .navbar .middle-right {
    margin-left: 10%;
  }
}

      </ul>
      <ul class="nav navbar-nav middle-right">
        <li><a href="#">Link</a>

        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li><a class="nav-link-custom" href="#">Sign In</a>

        </li>
      </ul>
    </div>
  </div>
</nav>

将margin CSS 包装在媒体查询中，这样它只会在扩展版本中影响文本。

@media (min-width: 768px) {
  .middle-left {
    margin-left: 25%;
  }

  .middle-right {
    margin-left: 10%;
  }
}
