alignment issue

[biatche]

there is a row of links At the top of my site. I want them left aligned to the same place as the search bar in the header.

The problem is that it looks fine on my screen, but if I open up the favourites to narrow the screen, it goes too far right.

I imagine that different sizes of screens give different results too.

My CSS looks like this -

.nav {
	position: relative;
        left: 250px;
	top: 5px;
	height: 5px; /* Is this necessary? */
	/* font: 1.2em Verdana, Sans-Serif; */
	font-size: 1.2em;
        font-weight: bold;
	color: #404040; /* Is this necessary? */
	}

.nav a {
	color: #a2b3bf;
	}

replace
left:250px;

with
margin-left:auto;
margin-right:auto;
