What are nav bars?

Think about it: your navigation is actually an unordered list of links.

Mark them up inside <ul> tags.

Horizontal Nav bars

We can use CSS to control how these lists are displayed on our pages.

By using display:inline we can create horizontal nav bars.

Here's the code used for this nav bar:

#nav1{
margin-top: 1em;
margin-bottom: 0.5em;
}

#nav1 ul {
background-color: silver;
text-align: center;
margin-left: 0;
padding-left: 0;
border-bottom: 1px solid gray
}

#nav1 li {
list-style-type: none;
padding: 0.25em 1em;
border-left: 1px solid white;
display: inline
}

#nav1 li:first-child {
border: none;
}

Vertical Navbars

Here's the code for this one:

#nav2 {
background-color: silver;
border: solid 1px gray;
width: 8em
}

#nav2 ul {
list-style-type: none;
margin: 0;
padding: 0;
border: none
}

#nav2 li {
margin: 0;
padding: 0.25em 0.5em 0.25em 1em;
border-top: 1px solid gray;
width: 100%;
display: block
}

html>body #nav2 li {
width: auto;
}

#nav2 li:first-child {
border: none
}
