How Does This Sample Menu Set The Height

I found this menu sample on W3Schools. I'm trying to create a menu bar on my MVC layout page. My was looking very sloppy and I liked how this one looks. I pasted it into my website and it works as shown, but I don't understand how it is being styled. I don't see any height or vertical alignment settings. Is it the padding style that does it? Are ul and li tags commonly used for this kind of menu? I would have used something like a span tag to do this and not ul or li tags.

<!DOCTYPE html>
ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;

li {
float: left;
border-right:1px solid #bbb;

li:last-child {
border-right: none;

li a {
display: block;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;

li a:hover:not(.active) {
background-color: #111;

.active {
background-color: #4CAF50;

<li><a class="active" href="#home">Home</a></li>
<li><a href="#news">News</a></li>
<li><a href="#contact">Contact</a></li>
<li style="float:right"><a href="#about">About</a></li>

The height is being set by the default CSS styling in addition to some padding applied to the links. The default CSS height for the ul element is auto, meaning that it will fill space (i.e. be as tall) as its children.

What this means is that it is taking the font-size / line-height of the links and adding padding, which is 14px on both top and bottom. That height becomes the height of the entire list / navigation bar.
