Answer 1

#cssmenu {
text-align: center;
}
#cssmenu ul {
display: inline-block;
}
#cssmenu ul li {
display: inline-block;
}
#cssmenu ul li a {
display: block;
/* Other Link styles here */
}

Answer 2

Hmm.. if it is okay that you use a Web Framework, I will use the MaterializeCSS framework because it makes things much easier.
<html>
<head>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.3/css/materialize.min.css">
</head>
<body>
<nav>
<ul class = "center">
<li>Home</li>
</ul>
</nav>
</body>
</html>
If you run the example above, "home" will be centered!

Basically, you need to get rid of your float: left on your li's and instead give them display: inline-block. Then you can use text-align: center on the parent ul to center your menu.
CodePen
#cssmenu > ul {
margin: 0
text-align: center;
}
#cssmenu > ul > li {
display: inline-block;
padding: 15px;
}
