Hi
Sorry I was away due to medical emergency.
I put the code in the custom css, but had no luck.
Later I edited the original style.css and put the following code –
.footer-column {
margin-bottom: -60px;
}
but still no luck.
I put the same in global customs css, again it didn’t work.
At last I put it in the customize -> additional css and it worked like a charm!
Thanks for your support.
