Vertically centering a div inside another div [duplicate]

Answer 1

I personally prefer the trick of using a hidden pseudo element to span the full height of the outer container, and vertically aligning it with the other content. Chris Coyier has a nice article on the technique. http://css-tricks.com/centering-in-the-unknown/ The huge advantage of this is scalability. You don't have to know the height of the content or worry about it growing/shrinking. This solution scales :).

Here's a fiddle with all the CSS you'll need and a working example. http://jsfiddle.net/m5sLze0d/

.center:before {
    content: ""; /* Adding Extra Space Above Element */
    display: inline-block;
    height: 100%;
    margin-right: -0.3em;
    vertical-align: middle;
}
.center_element {
    display:inline-block;
    float:none;
    vertical-align:middle;
    white-space:normal;
    text-align:left;
}
