Center a CSS dropdown menu - html

Question

This is my CSS code. I can't seem to get it centered. I've tried using display: inline-block and float: left. I've also tried using margins but it ends up messing up the dropdown box. I've tried editing everything but I can't get it right. I'm sorta new to this kinda thing. I would appreciate the help

Answer 1

Since you are using this:
nav ul {
display: inline-block;
}
To center that ul you can use text-align on the parent, try this:
nav {
text-align:center;
}
You can check this link http://jsfiddle.net/eb2Zd/6/ to review the demo file.

Answer 2

You can use this on the nav
nav {
text-align:center;
}

Answer 3

After providing us with a JsFiddle i have 2 examples for you.
Example 1:
You should give your nav a width and margin:0 auto; Like in the example down here.
nav { width:505px; margin: 0 auto}

Example 2:
nav { text-align:center; }

Answer 5

On the html, place inside a which must be centered.
On the CSS file, center by placing this
.center {position: relative;
margin-left:auto;
margin-right:auto;
text-align:center;
}
