CSS Question

How can I vertically center text in a dynamically height div?

<body>
<div style="position:absolute; height:100%; width:100%;">
<h1 style="text-align:center;">Text</h1>
</div>
</body>


How can I vertically center the h1 tag inside of the div tag, no matter how tall the div element is? i.e. If the user changes his browser height, I want the h1 to vertically align in the center, according to the new height.

Thanks.

Answer

The best solution I've ever encountered is to make use of the display property and set the wrapper element as a table to allow the usage of vertical-align:middle on the element to be centered:

See this working Fiddle Example!

HTML

<body>
    <div>
        <h1>Text</h1>
    </div>
</body>

CSS

body {width: 100%; height: 100%;}   /* this is just to "view" the div height...*/

div {
    position:absolute; height:100%; width:100%;
    display: table;
}
h1 {
    display: table-cell;
    vertical-align: middle;
    text-align:center;
}
