Answer 1

Better way to create sub menus is this
Replace your html with this
HTML
<div id="navigation">
<img class="weblogo"src="weblogo.png"></img>
<nav>
<ul>
<li class="active">home</li>
<li>work</li>
<li>about</li>
<li class="dropdown"><a onClick="toggleNavPanel('panel')" >services</a>
<div id="panel">
<div>
<ul>
<li>Search</li>
<li>Search</li>
<li>Search</li>
<li>Search</li>
</ul>
</div>
</div>
</li>
<li>contact</li>
</ul>
</nav>
And add this to your css
#panel {
position: absolute;
background-color: red;
height: 0;
width: 100px;
top: 120px;
transition: height 0.3s linear 0s;
overflow:hidden;
}
Add this javascript also
function toggleNavPanel(x) {
var panel = document.getElementById(x), maxH="300px";
if(panel.style.height == maxH) {
panel.style.height = "0px";
}else {
panel.style.height = maxH;
}
}
Also remove this from your css
nav ul li:hover > ul {
display: block;
}
