在调整大小时，div会在另一个上方射击

Question

这可能是一个简单的修复，但我似乎无法弄清楚什么是错的。我删除了所有不必要的东西，所以希望代码读起来不是太糟糕。

基本上，当您向下缩放页面时，宽度方面，页脚（联系人）与其上方的div重叠。在Code Pen上已经重叠了。

HTML：

<div class="library library-row specialties">
        <div class="container">
            <div class="desc">
                <h1>Our Specialties<br/></h3>
                <p>
                    Everything we can do for you
                </p>
            </div>
            <div class="row row-images">
                <div class="col-sm-4">
                    <i class="fa fa-database" aria-hidden="true"></i>
                    <h4>Databases</h4>
                </div>
                <div class="col-sm-4">
                    <i class="fa fa-server" aria-hidden="true"></i>
                    <h4>Servers</h4>
                </div>
                <div class="col-sm-4">
                    <i class="fa fa-cloud" aria-hidden="true"></i>
                    <h4>Cloud Integration</h4>
                </div>
            </div>
        </div>
    </div>

    <div class="footer library library-row">
        <div class="container">
            <div class="accounts">
                <i>
                    <a href="#" class="fa alt fa-facebook"></a>
                    <a href="#" class="fa alt fa-twitter"></a>
                    <a href="#" class="fa alt fa-instagram"></a>
                    <a href="#" class="fa alt fa-github"></a>
                    <a href="#" class="fa alt fa-envelope"></a>
                </i>
            </div>
        </div>
    </div>

CSS :(我无法粘贴它，很抱歉，但请从Code Pen中获取）

再次，对不起，如果这是一个基本修复。我试过了，但我不确定它有什么问题。

有一些CSS应用于.specialties，它正在修复该div的高度。页脚位于该div下方，但.specialties div中的内容在div外部垂直溢出，因此内容呈现在页脚的下方和下方。

删除此高度：100vh; CSS，你可以看到为什么会发生这种情况。可能需要重构，如果你能解释设计意图，我很乐意帮助你。
