About Acid2 in brief
Acid2 is a webpage that test web browsers’ functionality in displaying aspects of HTML markup, CSS 2. 1 styling, PNG images, and data URIs. The test page was released on 13 April 2005 by the Web Standards Project. It was developed in the spirit of Acid1, a relatively narrow test of compliance with the Cascading Style Sheets 1. 0 standard. On 31 October 2005, Safari 2. 0. 2 became the first browser to pass Acid2. Opera, Konqueror, Firefox, and others followed. With the release of Internet Explorer 8 on 19 March 2009, the latest versions of all major desktop web browsers now pass the test until IE10 was released, which fails the test. Its successor, Microsoft Edge, is able to render it correctly as of Windows 10 version 1607.
Acid2 was followed by Acid3. While Acid2 primarily tests CSS, Acid3 focuses more on JavaScript and other \”Web 2.0\” technologies. The Acid2 test fails when browsers become compliant with current CSS collapse and margin standards. As such, IE8 will not pass the acid2 test if such settings are not turned on by default for pages loaded in the \”Intranet Zone” This zone is named after UNC, named without dots, and addresses sites that bypass the test by using a proxy that is active in this zone. It is also named after the acid test for gold, it was developed by Håkon Lie, chief technical officer of Opera Software.
