twitter-bootstrap - 在响应式 Bootstrap 导航栏中垂直居中链接时出现问题

Question

我已经为此苦思冥想了一段时间。我猜我缺少一个简单的解决方案或技巧。我试过调整链接、li 和它们周围的容器的填充和边距。无论屏幕大小如何，我都希望它们在导航栏中保持垂直居中。现在，当视口(viewport)调整大小时，它们会上下移动。我的代码如下:

/* Style for Navbar/Header */
nav.navbar {
    padding: 0 1% 0 1%;
}

.navbar, 
.dropdown-menu {
    background-image: url(../images/pw_maze_black_@2X.png);
}

.navbar .navbar-nav > li > a:hover,
.navbar .navbar-nav > li > a:focus, 
.dropdown-menu > li > a:hover, 
.dropdown-menu > li > a:focus {
    background-color: #656864 !important;
    color: white;
}

ul.nav.navbar-nav.navbar-right.collapse.navbar-collapse {
    background: red;
    margin-top: 5%;
}

.navbar .navbar-nav > li > a {
    font-family: "bodoni mt condensed", serif;
    font-size: 3.6vw;
    color: #a5a7a4;
    padding-top: 60px;
    padding-bottom: 60px;
}

.dropdown-menu > li > a {
    line-height: 100%;
    font-family: "bodoni mt condensed", serif;
    font-size: 2.5vw;
    color: #a5a7a4;
}

.links-container {
    
}

#logo-bar {
    width: 100%;
}

.navbar-toggle {
    background-color: #a5a7a4;
    position: static;
    padding: 2%;
    margin-top: 61px;
    margin-right: 40px;
    margin-bottom: 0;

}

div.navbar-header.nav.navbar-nav {

}

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

/* End of navbar style */

                        <li><a href="our-work.html">Our Work</a></li>
                        <li class="divider"></li>
                        <li><a href="https://www.facebook.com/arrowsedgedesign/">Facebook</a></li>
                    </ul>
                </li>
                <li><a href="contact-us.php" class="option">Contact Us</a></li>
            </ul>
            </div>
        </div>
    </nav>

    <!-- end of HTML for navbar -->

您可以通过更改导航栏元素的行高来实现这一点。

.navbar .nav li a {
  line-height: 50px;
}

根据需要为每个视点更改 50px 值，文本应始终垂直居中。
