Not in the middle of the page, as in margin: 0 auto;
I'm talking about in the center as in top to bottom.
Thank you in advance!

Answer 1

With html5 this is pretty easy using flexbox:
This article discribes how to do it
http://coding.smashingmagazine.com/2013/05/22/centering-elements-with-flexbox/
and here is the demo (also from the article)
http://jsfiddle.net/pnNqd/
HTML:
<h1>OMG, I’m centered</h1>
CSS:
html {
height: 100%;
}
body {
display: -webkit-box; /* OLD: Safari, iOS, Android browser,
older WebKit browsers. */
display: -moz-box; /* OLD: Firefox (buggy) */
display: -ms-flexbox; /* MID: IE 10 */
display: -webkit-flex; /* NEW, Chrome 21+ */
display: flex; /* NEW: Opera 12.1, Firefox 22+ */
-webkit-box-align: center; -moz-box-align: center; /* OLD… */
-ms-flex-align: center; /* you know the drill now… */
-webkit-align-items: center;
align-items: center;
-webkit-box-pack: center; -moz-box-pack: center;
-ms-flex-pack: center;
-webkit-justify-content: center;
justify-content: center;
margin: 0;
height: 100%;
width: 100%; /* needed for Firefox */
}
h1 {
display: -webkit-box; display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-align: center; -moz-box-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;
height: 10rem;
}

There are multiple ways:
position: absolute;
left: 50%;
top: 50%;
margin-left: <50% of width from element>;
margin-top: <50% of height from element>;
or:
HTML
<div id="content-wrapper">
<div class="wrapper">
Some text
</div>
</div>
CSS
#content-wrapper {
display: table;
width: 100%;
height: 100%;
text-align: center;
}
.wrapper {
display: table-cell;
vertical-align: middle;
position: relative;
}
note: This won't work every time.. I did this on my own site.

Answer 3

The easiest way if your div is absolutely positioned. Conditions. Your div must have a fixed width and height
#myBox{width:50px; height: 50px; position: absolute; margin: auto; top: 0; left: 0; bottom: 0; right: 0; border:solid 1px #000;}
See http://jsfiddle.net/zM2J2/
Put a border to show you an outline.
