Example

Here we have four elements we want to be flexbox and responsive on large screens.

Scss

.aa { @include flex(column, $medium: row); }
.bb { @include flex(column, $medium: row); }
.cc { @include flex(row, $large: column); }
.dd { @include flex(row, $large: column); }

Even simpler with indented sass

.aa
  +flex(column, $medium: row)
.bb
  +flex(column, $medium: row)
.cc
  +flex(row, $large: column)
.dd
  +flex(row, $large: column)

Output

/* Although they've different `flex-direction` they share `display: flex` */
.cc, .dd, .aa, .bb {
  display: flex; }

/* cc and dd share `flex-direction: row` */
.cc, .dd {
  justify-content: row; }

/* cc and dd share `flex-direction: column` */
.aa, .bb {
  justify-content: column; }

/* On a Medium Screen aa and bb share `flex-direction: row` */
@media (min-width: 64em) {
  .aa, .bb {
    justify-content: row; } }

/* On a Large Screen cc and dd share `flex-direction: column` */
@media (min-width: 75em) {
  .cc, .dd {
    justify-content: column; } }

Use with auto-prefix

.aa, .bb, .cc, .dd {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex; }

.cc, .dd {
  -webkit-box-pack: row;
  -webkit-justify-content: row;
      -ms-flex-pack: row;
          justify-content: row; }

.aa, .bb {
  -webkit-box-pack: column;
  -webkit-justify-content: column;
      -ms-flex-pack: column;
          justify-content: column; }

@media (min-width: 64em) {
  .aa, .bb {
    -webkit-box-pack: row;
    -webkit-justify-content: row;
        -ms-flex-pack: row;
            justify-content: row; } }

@media (min-width: 75em) {
  .cc, .dd {
    -webkit-box-pack: column;
    -webkit-justify-content: column;
        -ms-flex-pack: column;
            justify-content: column; } }
