Horizontal centering text over image via CSS

Issue

Consider the following html:

<div class="image">
    <img src="sample.png"/>
    <div class="text">
       Text of variable length
    </div>
</div>

Where:

.image {
    position:relative;
    text-align:center; // doesn't work as desired :(
}

.text {
    position:absolute;
    top:30px;
}

Can you please tell, if there is a way to horizontally align the text in the center of the .image div? I can't use the left property, since the length of the text is unknown and the text-align property doesn't work for the .text div :(

Thank you.

Solution

Try the following CSS:

.image {
    position:relative;
}

.text {
    left: 0;
    position:absolute;
    text-align:center;
    top: 30px;
    width: 100%
}
