//  # Responsive
//  Magento UI library provides a strong approach for working with media queries. It`s based on recursive call of <span style="white-space: nowrap"><code>.media-width()</code></span> mixin defined anywhere in project but invoked in one place in <span style="white-space: nowrap"><code>lib/web/css/source/lib/_responsive.less</code></span>. That's why in the resulting <code>styles.css</code> we have every media query only once with all the rules there, not a multiple calls for the same query.
//
//  To see the media queries work resize window to understand which breakpoint is applied.
//  ```
//  <div class="example-responsive-block">
//      are applied.
//  </div>
//  ```

.example-responsive-block {
    padding: 10px;
}

.media-width(@extremum, @break) when (@extremum = 'max') and (@break = @screen__m) {
    .example-responsive-block {
        background: #ffc;
    }
    .example-responsive-block:before {
        content: 'Mobile styles ';
        font-weight: bold;
    }
}

.media-width(@extremum, @break) when (@extremum = 'min') and (@break = @screen__m) {
    .example-responsive-block {
        background: #ccf;
    }
    .example-responsive-block:before {
        content: 'Desktop styles ';
        font-weight: bold;
    }
}

//  # Responsive mixins usage
//
//  For grouping style rules in certain media queries .media-width() mixin used.
//  ```css
// .media-width(<@extremum>, <@break>);
//  ```
//  <span style="white-space: nowrap"><code>@extremum: max|min</code></span> - sets whether to use **min-width** or **max-width** in media query condition<br />
//  <span style="white-space: nowrap"><code>@break: value</code></span> - sets the value of breakpoint to compare with in media query condition.<br />
//  For example
//  ```css
//  .media-width(@extremum, @break) when (@extremum = 'max') and (@break = @screen__s) {
//      your styles
//  }
//  ```
//  It will be complied to
//  ```css
//  @media only screen and (max-width: 640px) {
//      your styles
//  }
//  ```
//  &nbsp;
//
//  # Media query style groups separation variables
//
//  <code>@media-common: true|false</code> - sets whether to output common styles.
//  For common styles every time you want to add some styles you should use
//  ```css
//  & when (@media-common = true) {
//      your styles
//  }
//  ```
//
//  <code>@media-target: all|desktop|mobile</code> - Sets target device for styles output
//  ```css
//  & when (@media-target = 'mobile'),
//  (@media-target = 'all') {
//     @media only screen and (max-width: (@screen__xs - 1)) {
//         .media-width('max', @screen__xs);
//     }
// }
//  ```
//
//  ## Gathering
//
//  Everything that you include in collector mixins above will go in place where they declared.
//  As example all
//  ```css
//  .media-width(@extremum, @break) {
//      your code
//  }
//  ```
//  Will go to
//  ```css
//  .media-width(@extremum, @break));
//  ```
//  By default you can find it <code>_responsive.less</code> file in li
//  &nbsp;
//
//  # Responsive breakpoints
//  In Magento UI library there are predefined variables for breakpoints.
//  ```css
//  @screen__xxs: 320px;
//  @screen__xs: 480px;
//  @screen__s: 640px;
//  @screen__m: 768px;
//  @screen__l: 1024px;
//  @screen__xl: 1440px;
//  ```
