Vertically Centering a DIV on an HTML page

Question

How can I vertically center my DIV on the HTML page? I thought by setting the margin to 0 auto would do the trick, however that doesn't appear to be the case as it only horizontally centers and doesn't also vertically center my #main div on the page.

Here is a quick fiddle: https://jsfiddle.net/stevdbbz/

Here is the HTML and CSS in question:

<!DOCTYPE html>

<html>

<head>

<style type="text/css">
* {
    font-family: Segoe UI;
    font-size: 9pt;

    padding: 0;
    margin: 0;
}
#main {
    border: 1px solid rgb(180,180,180);
    width: 800px;
    height: 650px;
    margin: 0 auto;
}
#boxA {
    padding-top: 7px;
    padding-bottom: 7px;

You can vertically center an element relative to the viewport using 3 simple rules:

#main {
    position: relative;
    top: 50vh; // positions the top edge of the element 50% down the viewport
    margin: -325px auto 0; // moves the top edge down the element by 325px (650px height / 2)

    border: 1px solid rgb(180,180,180);
    width: 800px;
    height: 650px;
}

If your viewport is smaller than your content, you will not be able to see the top of the `main` div – Pete Nov 16 '15 at 15:47

You can use flexbox. Here is an example:

<div class="middle-align">
        <p>This is a vertically centered paragraph</p>
    </div>
</div>

and for the css

.middle-align {
    height:400px;
    background-color:gray;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -ms-flex-align: center;
    -webkit-align-items: center;
    -webkit-box-align: center;
    align-items: center;
}
