// User Interface
// This file can be expanded to handle all the user interface properties as
// they become available in browsers:
// http://www.w3.org/TR/2000/WD-css3-userint-20000216

// The prefixed support threshold for user-select.
// Defaults to the $graceful-usage-threshold.
$userselect-support-threshold: $graceful-usage-threshold !default;

// This property controls the selection model and granularity of an element.
//
// @param $select
//   [ none | text | toggle | element | elements | all | inherit ]
@mixin user-select($select) {
  $select: unquote($select);

  @include with-each-prefix(user-select-none, $userselect-support-threshold) {
    // old Firefox used a proprietary `-moz-none` value, starting with Firefox 21 `none` behaves like `-moz-none`
    // @link https://developer.mozilla.org/en-US/docs/Web/CSS/user-select
    @include prefix-prop(user-select, if($current-prefix == -moz and $select == 'none', -moz-none, $select));
  }
}

// The prefixed support threshold for input-placeholder.
// Defaults to the $graceful-usage-threshold.
$input-placeholder-support-threshold: $graceful-usage-threshold !default;

// Style the html5 input placeholder in browsers that support it.
//
// The styles for the input placeholder are passed as mixin content
// and the selector comes from the mixin's context.
//
// For example:
//
//     #{elements-of-type(text-input)} {
//       @include input-placeholder {
//         color: #bfbfbf;
//         font-style: italic;
//       }
//     }
//
// if you want to apply the placeholder styles to all elements supporting
// the `input-placeholder` pseudo class (beware of performance impacts):
//
//     * {
//       @include input-placeholder {
//         color: #bfbfbf;
//         font-style: italic;
//       }
//     }
@mixin input-placeholder {
  @include with-each-prefix(css-placeholder, $input-placeholder-support-threshold) {
    @if $current-prefix == -webkit {
      &::-webkit-input-placeholder { @content; }
    }
    @else if $current-prefix == -moz {
      // for Firefox 19 and below
      @if support-legacy-browser("firefox", "4", "19", $threshold: $input-placeholder-support-threshold) {
        &:-moz-placeholder { @content; }
      }
      // for Firefox 20 and above
      &::-moz-placeholder { @content; }
    }
    @else if $current-prefix == -ms {
      &:-ms-input-placeholder { @content; }
    }
  }
  // This is not standardized yet so no official selector is generated.
