White space appears when responsive website is resized
<p>I have a responsive website using bootstrap in which almost every element animates in with WOWjs (animates in as you scroll by it.) When I resize the document to test its responsiveness then scroll all the way down, then open it up in full screen, I'm way under the footer. I inspected the element and that white space isn't part of anything. Not even the body. In fact, I can't highlight it and it appears under the body element. I'm very confused by this. It may be WOWjs because I have encountered similar things while using WOWjs in other projects. Removing WOWjs is not an option as this is for a client and he wants it. I have tried adding <code>height: 100%</code> and this results in WOWjs elements to not fade in. I have also tried <code>margin: 0; 
padding: 0;</code> and it still doesn't work. I can't attach the code because it requires way too much assets and its over 300 codes and I don't know where the problem is. I can give you some code that may, or atleast i think may, be relevant.</p>

<pre><code>body {
padding:0;
margin:0;
overflow-x: hidden;
}

*{
 margin:0;
 padding:0;
}
</code></pre>

<p>Maybe someone has background on WOWjs and animatecss and viewport to resolve the problem. </p>

<p>PS.. The website is a php document as it has a contact form.</p>
