I am trying to align (and stack) some images inside a bootstrap grid.
For some reason, the images aligns to the window and not the grid.
I use position:absolute which work like this (http://www.w3schools.com/):
"An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is <html>"
Here is a jsfiddle : http://jsfiddle.net/sbE6t/
.rings img {
position:absolute;
top: 0px;
left: 0px;
}
