factoids
Acid2 is a test page published and promoted by the Web Standards Project to expose web page rendering flaws in web browsers and other applications that render HTML. Named after the acid test for gold, it was developed in the spirit of Acid1, a relatively narrow test of compliance with the Cascading Style Sheets 1.0 (CSS1) standard, and was released on 13 April 2005. As with Acid1, an application passes the test if the way it displays the test page matches a reference image.Acid2 tests aspects of HTML markup, CSS 2.1 styling, PNG images, and data URIs. The Acid2 test page will be displayed correctly in any application that follows the World Wide Web Consortium and Internet Engineering Task Force specifications for these technologies. These specifications are known as web standards because they describe how technologies used on the web are expected to function.Acid2 was designed with Microsoft Internet Explorer particularly in mind. The creators of Acid2 were dismayed that Internet Explorer did not follow web standards. It was prone to display web pages differently from other browsers, causing web developers to spend time tweaking their web pages. Acid2 challenged Microsoft to make Internet Explorer comply with web standards.Acid2 was released on 13 April 2005. 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.The test fails when browsers become compliant with current CSS collapse and margin standards.WEB,weblink Margin Collapse Issue,

, In a 16 March 2005 article on CNET, Lie expressed dismay that Microsoft Internet Explorer did not properly support web standards and hence was not completely interoperable with other browsers. He announced that Acid2 would be a challenge to Microsoft to design Internet Explorer 7, then in development, to achieve a greater degree of standards compliance than previous versions of Internet Explorer. The original Acid1 test had forced browser makers to fix their applications or face embarrassment; Lie hoped that Acid2 would do the same.WEB

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.WEB,weblink Standards and CSS in IE, Wilson, Chris, IEBlog, Microsoft, 29 July 2005, 11 March 2008

It is what it looks currently in IE8 and it will look exactly like this when we ship IE8 because we are not breaking any compatibility, and this is a compatible mode of IE8. And, uh, most of the web relies on particular behavior including particular incorrect behavior, so the incorrect behavior will still be there unless the new content wants IE to be in standards-compliant mode, and then they will ask us, and then we will show perfectly standard picture.", WEB

Acid2 tests a variety of web standards published by the World Wide Web Consortium and the Internet Engineering Task Force.

  • Alpha transparency in PNG-format images: The eyes of the smiley face use alpha transparency, which is part of the 1996 Portable Network Graphics specification. Alpha transparency blends the eyebrows into the face smoothly and elegantly. This was a significant issue because Internet Explorer 6, the most widely used web browser at the time Acid2 was released,WEB

  • The object element: The eyes also test support of the HTML object element.

weblink" title="web.archive.org/web/20080727143129weblink">weblink> archivedate= 27 July 2008, no, yet by 2005 it still was not completely supported in all web browsers. The creators of Acid2 considered object element support important because it allows for content fallback—if an object fails to load, then the browser can display alternative (generally simpler, more reliable) content in its place.
  • Data URIs: The actual images that form the eyes are encoded as data URIs, which allow multimedia to be embedded in web pages rather than stored as a separate file. Acid2 tests the most common case, where a binary image is base64-encoded into text and then that encoded text is included in a data URI in the web page. Although the IETF published the data URI specification in 1998, they never formally adopted it as a standard.WEB,weblink Proposed Standards, Official Internet Protocol Standards, Internet Society, 4 January 2009, 4 January 2009

  • Absolute, relative, and fixed CSS positioning: Absolute positioning means that the web developer specifies the exact X and Y coordinates where an element is to be placed into the page. Relative positioning means that the web developer specifies an X and Y offset from the usual position of the element. Fixed positioning means that the element is placed relative to the browser window, and scrolls with the window rather than with the rest of the page.WEB,weblink Visual formatting model, Cascading Style Sheets, level 2 revision 1, Bos, Bert

Acid2 not only retests margin support but also tests minimum and maximum heights and widths, features new to CSS 2.0.
  • CSS table formatting: This part of CSS allows the web designer to apply table formatting without traditional HTML table markup.
  • CSS generated content: Using CSS generated content, web developers can add decorations and annotations to specified elements without having to add the content to each one individually.
  • CSS parsing: A number of illegal CSS statements are present in Acid2 to test error handling. Standards-compliant browsers are expected to handle these errors as the CSS specification directs. This helps ensure cross-browser compatibility by making all browsers treat CSS with the same level of strictness, so that what works in one browser should not cause errors in another.
  • Paint order: Acid2 requires that the browser has standard paint order. That is, overlapping elements should be placed or painted on top of each other in the correct order.
  • Hovering effects: When the user moves his or her mouse over the smiley face's nose, it turns blue. This is called a hovering effect, and while it has traditionally been used for hyperlinks, it should work on a wide variety of HTML elements.WEB,weblink Details on our CSS changes for IE7, Mielke, Markus, IEBlog, Microsoft, 22 August 2006, 31 July 2008

A variant of the Acid2 test that does not test for data URI support is also available from the Web Standards Project.

Passing conditions

A passing score is only considered valid if the browser's default settings were used. Actions such as changing font sizes, zoom level, and applying user stylesheets can break the display of the test. This is expected and is not relevant to a browser's compliance.WEB
