Wrong(?) media queries in .make-xs-column-*

Created by: nenebale

Hi :)

The media queries in the three .make-xs-column-* mixins make them ineffective under a viewport width of @screen-xs-min.

Am I using them wrong (see example below) or are this media queries misplaced?

Thank you for your help!

My code:

.logo {
  background: url('logo-text.svg') left top no-repeat;
  background-size: 100% auto;
  height: 200px;

  @include make-xs-column(8);
  @include make-xs-column-offset(2);

  @include make-sm-column(5);
  @include make-sm-column-offset(3.5);

  @include make-md-column(4);
  @include make-md-column-offset(4);

  @include make-lg-column(3);
  @include make-lg-column-offset(4.5);
}

Mixins:

.make-xs-column-offset(@columns) {
  @media (min-width: @screen-xs-min) {
    margin-left: percentage((@columns / @grid-columns));
  }
}
.make-xs-column-push(@columns) {
  @media (min-width: @screen-xs-min) {
    left: percentage((@columns / @grid-columns));
  }
}
.make-xs-column-pull(@columns) {
  @media (min-width: @screen-xs-min) {
    right: percentage((@columns / @grid-columns));
  }
}
