I am searching for the following solution. In my CSS I have the following:
img, a img { max-width: 100%; vertical-align: middle; }
Ensure that your #pixel-perfect img CSS declaration is BELOW the img, a img declaration, otherwise it will get overwritten.
#pixel-perfect img
img, a img
#pixel-perfect img { max-width: none; width: auto; position: absolute; margin: -200px 0 0 -140px; z-index: -9999; }
