Html 强制引导固定页脚内的图像在手机分辨率上水平对齐

我正在尝试将社交图像水平放置在手机上，在更高分辨率下效果很好，但当我切换到手机分辨率时，图像会垂直对齐，并将页脚延伸到内容上，代码如下所示：

<!-- Footer -->
<footer>
    <nav id="top-nav" class="navbar navbar-inverse navbar-fixed-bottom custom-footer">
        <div class="container ">
            <div class="navbar-header">
                <a class="navbar-brand" href="#">
                    <img id="logo-fot" alt="BeBandSM" src="img/logo-fot.png">
                </a>
            </div>
                <ul class="nav navbar-nav navbar-right">
                    <li><a href="#"><img class="social-media-img" src="img/facebook.png" alt=""></a></li>
                    <li><a href="#"><img class="social-media-img" src="img/google_plus.png" alt=""></a></li>
                    <li><a href="#"><img class="social-media-img" src="img/twitter.png" alt=""></a></li>
                    <li><a href="#"><img class="social-media-img" src="img/youtube.png" alt=""></a></li>
                </ul>
        </div>
    </nav>
</footer>

结果: 高分辨率。

如何修复它？

将引导浮动css类“向左拉”添加到每个列表元素中应该可以做到这一点，例如：

<ul class="nav navbar-nav navbar-right">
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/facebook.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/google_plus.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/twitter.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/youtube.png" alt=""></a></li>
</ul>

<ul class="nav navbar-nav navbar-right">
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/facebook.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/google_plus.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/twitter.png" alt=""></a></li>
    <li class="pull-left"><a href="#"><img class="social-media-img" src="img/youtube.png" alt=""></a></li>
</ul>
