Link in sticky footer not clickable in Firefox and Chrome

Question

I am using a sticky footer like described in:

• How do you get the footer to stay at the bottom of a Web page?

Answer 1

Correct me if I'm wrong but I think you should add a negative value for z-index which pushes it back enabling the link button.

This worked for me

.footer, .push {
    height: 4em;
    position: relative;
    width: 90%;
    margin: 0 auto;
    z-index: -9000;
}
