Example

jQuery plugin

Style for hidden Markup that make CSS Breakpoints available in JavaScript via Media-Queries and visibility.

<style>

  [data-device-selector-item] {
    display: none;
  }
  @media
  only screen and (max-width: 768px) {
    [data-device-selector-devicetype="mobile"] {
      display: block !important;
    }
  }
  @media
  only screen and (min-width: 769px) and (max-width: 960px) {
    [data-device-selector-devicetype="tablet"] {
      display: block !important;
    }
  }
  @media
  only screen and (min-width: 961px) and (max-width: 1200px) {
    [data-device-selector-devicetype="desktop"] {
      display: block !important;
    }
  }
  @media
  only screen and (min-width: 1201px) {
    [data-device-selector-devicetype="large-desktop"] {
      display: block !important;
    }
  }
  @media
  only screen and (-webkit-min-device-pixel-ratio: 2),
  only screen and (   min--moz-device-pixel-ratio: 2),
  only screen and (     -o-min-device-pixel-ratio: 2/1),
  only screen and (        min-device-pixel-ratio: 2),
  only screen and (                min-resolution: 192dpi),
  only screen and (                min-resolution: 2dppx) {
    [data-device-selector-displaytype="retina"] {
      display: block !important;
    }
  }
</style>

Markup which make the visibility of Breakpoints available in JavaScript. The Markup should be added right before the closing body tag.

<div data-device-selector>
  <div data-device-selector-item data-device-selector-devicetype="mobile"></div>
  <div data-device-selector-item data-device-selector-devicetype="tablet"></div>
  <div data-device-selector-item data-device-selector-devicetype="desktop"></div>
  <div data-device-selector-item data-device-selector-devicetype="large-desktop"></div>
  <div data-device-selector-item data-device-selector-displaytype="retina"></div>
</div>

Initialise the jQuery Plugin and sample usage.

<script src="../node_modules/jquery/dist/jquery.min.js"></script>
<script src="../node_modules/js.device.selector/jquery.device.selector.min.js"></script>
<script>
  $.fn.deviceSelector();
  console.log($.fn.deviceSelector.getDeviceType()); // return mobile || tablet || desktop || large-desktop
  $('#deviceType').text($.fn.deviceSelector.getDeviceType());
  $('#displayType').text($.fn.deviceSelector.getDisplayType());
</script>

jQuery Plugin Custom

Use your own flavored Markup and pass your own settings to the Device Selector.

<style>

  .namespace__m-device-selector__item {
    display: none;
  }
  @media
  only screen and (max-width: 768px) {
    [data-ds-devicetype="m"] {
      display: block !important;
    }
  }
  @media
  only screen and (min-width: 769px) and (max-width: 960px) {
    [data-ds-devicetype="t"] {
      display: block !important;
    }
  }
  @media
  only screen and (min-width: 961px) and (max-width: 1200px) {
    [data-ds-devicetype="md"] {
      display: block !important;
    }
  }
  @media
