CSS for Width and Centering

Trying to center a 3 column div element with CSS class as you suggested in an earlier thread. So I did this

#ebs {
width: 130.141em;
margin-left: auto;
margin-right: auto;
}

That centered it, but broke responsiveness.

So then I did this

#ebs {
max-width: 130.141em;
margin-left: auto;
margin-right: auto;
}

Then it was back to being responsive, but was no longer centered on desktop.

Also tried percentage widths and parent/child div’s without results.

How can I center the columns using div-block like you suggested but ALSO keep it responsive?
