== 歷史 ==
Google員工[[伊恩·希克森]]於2007年4月開始進行測試，但開發進展緩慢。2007年12月，工作重新啟動。2008年1月10日，當時Anne van Kesteren在部落格中提到了該項目，該項目引起公眾關注<ref>{{cite web|last=van Kesteren|first=Anne|date=2008-01-10|url=http://annevankesteren.nl/2008/01/acid3|title=Acid3|accessdate=2008-03-04|archiveurl=https://web.archive.org/web/20080307125615/http://annevankesteren.nl/2008/01/acid3|archivedate=2008-03-07|deadurl=no}}</ref>。

在Acid3推出時，沒有任何一款軟體能通過測試<ref>{{cite web |url=http://webkit.org/blog/101/back-to-basics/ |title=The WebKit browser engine running under the Safari browser UI |publisher=[[WebKit]].org |date=2007-04-08 |first=Adele |last=Peterson |accessdate=2010-02-09 |archive-date=2010-06-12 |archive-url=https://web.archive.org/web/20100612212424/http://webkit.org/blog/101/back-to-basics/ |dead-url=no }}</ref><ref>{{cite web |url=http://webkit.org/blog/280/full-pass-of-acid-3/ |title=Full Pass of Acid3 |date=2008-09-25 |accessdate=2010-02-09 |first=Maciej |last=Stachowiak |publisher=[[WebKit]].org |archive-date=2013-07-06 |archive-url=https://www.webcitation.org/6Huzhxj9S?url=https://www.webkit.org/blog/280/full-pass-of-acid-3/ |dead-url=yes }}</ref>。及至推出後不到一個月，[[Presto]]<ref name="operaandacid3test">{{cite web |url=http://my.opera.com/desktopteam/blog/2008/03/26/opera-and-the-acid3-test |title=Opera and the Acid3 Test |author=Tim Altman |date=2008-03 |accessdate=2008-03-28 |publisher=[[Opera Software]] |archiveurl=https://web.archive.org/web/20080328170407/http://my.opera.com/desktopteam/blog/2008/03/26/opera-and-the-acid3-test |archivedate=2008-03-28 |deadurl=no }}</ref><ref name="operapublicbuild">{{cite web |url=http://labs.opera.com/news/2008/03/28/ |title=Public Acid3 build |quote=The latest post-9.5 build scores 99/100 and fails the smoothness criterion. |author=Lars Erik Bolstad |publisher=[[Opera Software]] |date=2008-03 |accessdate=2008-03-28 |archiveurl=https://web.archive.org/web/20080401082723/http://labs.opera.com/news/2008/03/28/ |archivedate=2008-04-01 |deadurl=yes }}</ref>和[[WebKit]]<ref name=r31356>{{cite web|title=WebKit achieves Acid3 100/100 in public build|url=http://webkit.org/blog/173/webkit-achieves-acid3-100100-in-public-build/|date=2008-03-26|author=Maciej Stachowiak|publisher=[[WebKit]].org|accessdate=2008-03-26|archiveurl=https://web.archive.org/web/20080328232249/http://webkit.org/blog/173/webkit-achieves-acid3-100100-in-public-build/|archivedate=2008-03-28|deadurl=no}}</ref><ref>{{cite web |url=http://www.maximumpc.com/article/news/safari_4_beta_first_browser_hit_a_perfect_acid3_test_score |title=Safari Beta 4 is the First Browser to Hit a Perfect Acid3 Test Score |author=Paul Lilly |publisher=Maximum PC |date=2008-09-29 |accessdate=2009-11-16 |archive-date=2009-05-25 |archive-url=https://web.archive.org/web/20090525044706/http://www.maximumpc.com/article/news/safari_4_beta_first_browser_hit_a_perfect_acid3_test_score |dead-url=no }}</ref>引擎的測試版本已成功取得100分。

2008年4月1日，[[Opera电脑浏览器|Opera]]曾聲稱其測試版的Acid3分數達到106分，不過後來證實是[[愚人節]]的玩笑<ref>{{cite web

2011年9月17日，伊恩·希克森與[[哈肯·維姆·萊]]（Opera軟體公司）宣布針對Acid3測試作了調整和變化，這將讓更多的瀏覽器可以通過測試<ref>{{cite web | url=https://plus.google.com/107429617152575897589/posts/JdHnqpuUER4 | title=Ian Hickson announces Acid3 modifications | date=2011-09-17 | accessdate=2011-09-17 | archive-date=2011-10-12 | archive-url=https://web.archive.org/web/20111012170339/https://plus.google.com/107429617152575897589/posts/JdHnqpuUER4 | dead-url=no }}</ref>。

Acid3測試調整之後，Firefox 4和Internet Explorer 9拿到了100分，然而Internet Explorer 9的測試結果與真正滿分的效能和外觀有些差異，直到Internet Explorer 10才正式通過測試<ref>{{cite web | url=http://www.tomsguide.com/us/acid3-browser-test-web-standard-compatibility-IE9,news-12583.html | title=Acid3 Test Simplified; All Modern Browsers Score 100 | date=2011-09-20 | accessdate=2013-06-07 | archive-url=https://web.archive.org/web/20130502100411/http://www.tomsguide.com/us/acid3-browser-test-web-standard-compatibility-IE9,news-12583.html | archive-date=2013-05-02 | dead-url=yes }}</ref>。
