Lowering the drop-up menu by 10px - html

Question

I'm having a little positioning error and I'm sure it's a simple fix, but after trying lots of different combinations of margin and padding, I can't get it perfect. The problem is I can't seem to get my drop-up menu (footer-nav ul ul) to move down 10px when it appears by hovering over #info. If I remove the margin from the css under #info, it drops the footer-nav ul ul down 10px where I need it, but it removes the 10px margin between the black box (streaks-content) and the footer-nav. Anyone know how to fix this? I appreciate it so so much! I don't know what I would do without you geniuses!
Here is the JS Fiddle: https://jsfiddle.net/fe2zk4L8/19/
Here is the html:
<header id="header">
<div id="nav">
<ul>
<li id="projects">PROJECTS
<ul>
<li id="one"> ONE </li>
<li id="two"> TWO </li>
<li id="three"> THREE </li>
<li id="four"> FOUR </li>
</ul>
</li>
</ul>
</div>
</header>
<div id="color">
<div id="streaks-content">
</div>
</div>
<footer id="footer">
<div id="footer-nav">
<ul>
<li id="info">INFO
<ul>
<li id="twitter">
TWITTER
</li>
<li id="instagram">
INSTAGRAM
</li>
<li id="email">

</div>
</footer>

Answer 1

Please add to the following CSS selector #footer-nav ul li:hover>ul that rule padding-bottom: 0;
so, in total you should have:
#footer-nav ul li:hover>ul {
display: block;
position: absolute;
bottom: 100%;
text-align: center;
margin: 0 auto;
left: 0;
right: 0;
padding-bottom: 0;
}
