Question

i cant get this navigation bar to center. Please help.
Here is my html:
<div class="nav">
<ul id="menu">
<li>Home</li>
<li>Latest News</li>
<li>Results & Events</li>
<li>Fundraising</li>
<li>Gallery</li>
</ul>
</div>
Here is my css:
#nav {
margin:0px auto; }
ul {
display: inline-block;
list-style-type:none;
margin:0 auto;
padding:0;
position: absolute; }
li {
display:inline;
float: left;
margin-right: 1px; }
li a {
display:inline-block;
min-width:140px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: Century Gothic, Candara, Tahoma, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none; }
li:hover a {
background: #659d32; }
li:hover ul a {
background: #f3f3f3;
color: #2f3036;
height: 40px;
line-height: 40px; }
li:hover ul a:hover {
background: #659d32;
color: #fff; }
li ul {
display: none; }
li ul li {
display: block;
float: none; }
li ul li a {
width: auto;
min-width: 100px;
padding: 0 20px; }
ul li a:hover + .hidden, .hidden:hover {
display: block; }
.show-menu {
font-family: Century Gothic, Candara, Tahoma, sans-serif;
text-decoration: none;
color: #fff;
background: #659d32;
text-align: center;
padding: 10px 0;
display: none; }
input[type=checkbox]{
display: none; }
input[type=checkbox]:checked ~ #menu{
display: block; }
#media screen and (max-width : 760px){
ul {
position: static;
display: none;
}
li {
margin-bottom: 1px;
}
ul li, li a {
width: 100%;
}
.show-menu {
display:block;
}
}
I tried adding a div around the whole thing and setting margin to auto but that hasnt worked. Im not sure what to do.

Answer 1

Firstly you're targeting #nav while it's .nav according to your html.
Then you need to set a width to your nav parent in order to have a centered position.
Working example
.nav {
margin:0px auto;
width:705px;
}
Edit: Since your list items and links aren't responsive, it doesn't make sense to add a percentage to the parent nav.
You can use something like this to have a responsive centered navigation:
.nav {
margin:0px auto;
width:90%;
}
ul {
list-style-type:none;
padding:0;
}
li {
float: left;
width:18%;
}
li a {
width:100%;
}

I think the reason why your auto margins didn't work is because you need to define a width on your wrapper. Also make sure that you are using the right selector # for id and . for class. Here's how id go about centering the navigation.
jsFiddle
<div class="wrapper">
<div class="nav">
<ul id="menu">
<li>Home</li>
<li>Latest News</li>
<li>Results & Events</li>
<li>Fundraising</li>
<li>Gallery</li>
</ul>
</div>
</div>
add this to your css:
.wrapper {
width:80%;
margin-left:auto;
margin-right:auto;
}

Answer 3

You almost had it, use:
.nav {
display: block;
margin: 0 auto;
width: 100%;
max-width: 960px;
}
You will simply need to adjust your max-width to move the navbar into the center (depending the width of your page container).
