Bootstrap 3: Text overlay on image

Answer 1

Is this what you're after?

http://jsfiddle.net/dCNXU/1/

I added :text-align:center to the div and image

Answer 2

Set the position to absolute; to move the caption area in the correct position

CSS

.post-content {
    background: none repeat scroll 0 0 #FFFFFF;
    opacity: 0.5;
    margin: -54px 20px 12px; 
    position: absolute;
}

Answer 3

You need to set the thumbnail class to position relative then the post-content to absolute.

Check this fiddle

.post-content {
    top:0;
    left:0;
    position: absolute;
}

.thumbnail{
    position:relative;

}

Giving it top and left 0 will make it appear in the top left corner.
