col-xs-0 Not Working Bootstrap

Question

When I emulate my mobile settings for my site, the social icons should be gone; however, they stay. I have tried putting col-xs-0 in the i frames themselves, and nothing.

Here's the picture:

Here's my footer HTML.

<footer>
    <div class="container-fluid">
            <div class="row">
                <div class="col-xs-0 col-md-2 pull-right footersocial">
                    <a href="#" target="_blank"><i class="fa fa-facebook-official fa-3x socialicons"  aria-hidden="true"></i></a>
                    <a href="#" target="_blank"><i class="fa fa-twitter fa-3x socialicons" aria-hidden="true"></i></a>
                    <a href="#" target="_blank"><i class="fa fa-instagram fa-3x socialicons" aria-hidden="true"></i></a>
                </div>
            </div>
        <div class="row" style="margin-left: 15px; margin-top: 15px;">
            <div class="col-md-2 text-center">
                <p>Privacy Policy</p>
            </div>
            <div class="col-md-2 text-center">
                <p>Terms of Service</p>
            </div>
            <div class="col-md-2 text-center">
                <p>Acceptable Use Policy</p>
            </div>
            <div class="col-md-2 text-center">
                <p>Warranty & Returns Policy</p>
            </div>
            <div class="col-md-2 text-center">
                <p>Third Party Copyright Notices</p>
            </div>
            <div class="col-md-2 text-center">
                <p>Terms of Service for Phone</p>
            </div>
        </div>
    </div>
</footer>

My CSS:

.socialicons {
    color: white;
    margin-right: 10px;
    margin-top: 10px;
    margin: 0 auto;
    display: block;
}
.footersocial {
  margin: 0 auto;
  display: block;
}
.col-xs-0 {
    display: none;
}

Answer 1

You should use hidden-xs to hide the block in the mobile view or xs (extra small) views:

<div class="hidden-xs col-md-2 pull-right footersocial">

Answer 2

In Bootstrap 4 you can use:

.d-none .d-{screen size}-block

to hide an element depending on the size of the screen (xs, sm, md etc)

Answer 3

I just did:

.col-xs-0, 
.col-sm-0,
.col-md-0,
.col-lg-0 {
  flex: 0 0 0;
  max-width: 0;
}

As my goal was to make sliding animation "from nowhere" and it worked fine for me!
