Lie and a colleague, Ian Hickson, created the first draft of the test in February 2005. Ian Hickson coded the final test in collaboration with the Web Standards Project and the larger web community. It was officially released on 13 April 2005 and at that time, every web browser failed it spectacularly. On 23 April 2005, Acid2 was updated to fix a bug that made the mouth appear too close to the nose. After several complaints, the test was again updated in January 2006 to remove a test for unpopular SGML-style comments that were never widely implemented. In browsers that do not implement SGML-style comments, the original test displayed the word "ERROR" on the bottom part of the face. In March 2008, Ian Hickson released Acid3 as a follow-up to Acid2. While Acid2 primarily tests CSS, Acid3 focuses more on JavaScript and other "Web 2.0" technologies. Microsoft's response In July 2005, Chris Wilson, the Internet Explorer Platform Architect, stated that passing Acid2 was not a priority for Internet Explorer 7, describing the test as a "wish list" of features rather than a true test of standards compliance. In December 2007, Microsoft announced that all the changes required to pass Acid2 would be made available in Internet Explorer 8, but that the changes would not be turned on by default, meaning that IE8 would not actually pass the test. The concern was that switching to a new behavior would cause too many problems in web pages expecting Internet Explorer's old, non-compliant behavior. Then in March 2008 Microsoft released IE8 beta 1 and turned on the changes by default after all. James Pratt, product manager for IE8, explained that this decision was made so that "developers can spend more time building features and cool stuff, and less time just trying to tweak their sites across different browsers." Another unresolved standards compliance issue caused IE8 beta 1 to fail if not all elements of the test were hosted from the same server. In August 2008 Microsoft released IE8 beta 2, which resolved the issue. As of that beta, however, standards mode is not turned on by default for pages loaded in the "Intranet Zone". This zone is active for pages loaded via UNC paths, named addresses without dots (like http://mysite/), and sites that bypass the proxy settings. As such, IE8 will not pass the Acid2 test if loaded in these cases. Overview of
