How to override max-width for specific div?

Question

I am searching for the following solution. In my CSS I have the following:

img, a img { 
    max-width: 100%;
    vertical-align: middle; 
}

This code is necessary for my WordPress theme and responsive web design. Now I want to override max-width property to auto. When I do this, it doesn't override:

#pixel-perfect img {
    max-width: auto !important;
    position: absolute;
    margin: -200px 0 0 -140px;
    z-index: -9999;
}

What did I do wrong?

Answer 1

Are you just looking to unset the max-width property? If so, try:

#pixel-perfect img {
    max-width: none;
}
