I'm attempting to make an image span the full width of a parent element, but the parent element has a margin of 10px. This means that when I apply
#parent img {
position: absolute;
top:0;
left:0;
height: auto;
width: 100%
}
It only expands the image to the width of the parent... minus 10px on each side. How can I adjust the image to completely fill the width of the parent, disregarding the margin?
