- * jQuery Plugin highlightFade (jquery.offput.ca/highlightFade)
- * (c) 2006 Blair Mitchelmore (offput.ca) blair@offput.ca
- */
-/**
- * This is version 0.7 of my highlightFade plugin. It follows the yellow fade technique of Web 2.0 fame
- * but expands it to allow any starting colour and allows you to specify the end colour as well.
- *
- * For the moment, I'm done with this plug-in. Unless I come upon a really cool feature it should have
- * this plug-in will only receive updates to ensure future compatibility with jQuery.
- *
- * As of now (Aug. 16, 2006) the plugin has been written with the 1.0.1 release of jQuery (rev 249) which
- * is available from http://jquery.com/src/jquery-1.0.1.js
- *
- * A note regarding rgb() syntax: I noticed that most browsers implement rgb syntax as either an integer
- * (0-255) or percentage (0-100%) value for each field, that is, rgb(i/p,i/p,i/p); however, the W3C
- * standard clearly defines it as "either three integer values or three percentage values" [http://www.w3.org/TR/CSS21/syndata.html]
- * which I choose to follow despite the error redundancy of the typical behaviour browsers employ.
- *
- * Changelog:
- *
- * 0.7:
- * - Added the awesome custom attribute support written by George Adamson (slightly modified)
- * - Removed bgColor plugin dependency seeing as attr is customizable now...
- * 0.6:
- * - Abstracted getBGColor into its own plugin with optional test and data retrieval functions
- * - Converted all $ references to jQuery references as John's code seems to be shifting away
- * from that and I don't want to have to update this for a long time.
- * 0.5:
- * - Added simple argument syntax for only specifying start colour of event
- * - Removed old style argument syntax
- * - Added 'interval', 'final, and 'end' properties
- * - Renamed 'color' property to 'start'
- * - Added second argument to $.highlightFade.getBGColor to bypass the e.highlighting check
- * 0.4:
- * - Added rgb(%,%,%) color syntax
- * 0.3:
- * - Fixed bug when event was called while parent was also running event corrupting the
- * the background colour of the child
- * 0.2:
- * - Fixed bug where an unspecified onComplete function made the page throw continuous errors
- * - Fixed bug where multiple events on the same element would speed each subsequent event
- * 0.1:
- * - Initial Release
- *
