modernizr/src/prefixedCSS.js

Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.

define(['ModernizrProto', 'prefixed', 'domToCSS'], function(ModernizrProto, prefixed, domToCSS) {
  /**
   * prefixedCSS is just like [prefixed](#modernizr-prefixed), but the returned values are in
   * hyphen-case (e.g. `box-sizing`) rather than camelCase (boxSizing).
   *
   * @memberOf Modernizr
   * @name Modernizr.prefixedCSS
   * @optionName Modernizr.prefixedCSS()
   * @optionProp prefixedCSS
   * @access public
   * @function prefixedCSS
   * @param {string} prop - String name of the property to test for
   * @returns {string|boolean} The string representing the (possibly prefixed)
   * valid version of the property, or `false` when it is unsupported.
   * @example
   *
   * `Modernizr.prefixedCSS` is like `Modernizr.prefixed`, but returns the result
   * in hyphenated form
   *
   * ```js
   * Modernizr.prefixedCSS('transition') // '-moz-transition' in old Firefox
   * ```
   *
   * Since it is only useful for CSS style properties, it can only be tested against
   * an HTMLElement.
   *
   * Properties can be passed as both the DOM style camelCase or CSS style hyphen-case.
