Never again use media queries!

npm install sass-mediaquery-singleline --save

On your scss (with webpack), add:

@import '~sass-mediaquery-singleline/main';

So, you need to change the below sass variables to your respective layout viewport widths:

// default values
$deskSize: 1920;
$mobileSize: 375;

// custom available variables
$deskSize: 1920 !default;
$mobileSize: 375 !default;
$mobileIdentifier: 768 !default;
$considerMinimalFont: true !default;
  $minFont: 10 !default;
  $minFontResolution: 1280 !default;

• deskSize (Number) Desktop width defined by the designer layout

  @include attr(display, flex, block);  // display: flex on desk and display: block on mobile
  @include attr(flex-direction, false, column);  // media mobile with flex-direction: column, but on desk wasn't created
  @include mediaAttr(height, 100, 320);  // media max-width: 320px with height: 100[calculated]
