Acid1 is a test page for browsers. It was developed in October 1998 and was important in establishing baseline interoperability between early web browsers, especially for the CSS1 specification.

Name

Acid1 is short for "Acid test #1", a name which refers to a test designed to detect gold during the the gold rush of the 1850s. An acid test would produce a quick and obvious assessment of the quality of a piece of metal, analogous to how the Acid series of tests are designed to produce a clear indication of browser's compliance to web standards.

History

Acid1 was different from other test suites when it was first released; Acid1 tested many features on one page and provided a rasterized reference rendering. Currently all major browsers pass the Acid1 test. [ [http://www.sciactive.com/main/index.php?Itemid=1&id=133&option=com_content&task=view Acid Test Results in Popular Browsers] ] Acid1 was developed by Todd Fahrner, who was frustrated with the lack of stringent tests to improve browser interoperability. After looking at tests developed by Braden McDaniel that used reference renderings to clarify the intended result, Fahrner developed a comprehensive test that resulted in a quirky-looking graphic. In 1999, the test was incorporated into the CSS1 test suite as test number 5.5.26.c [ [http://www.w3.org/Style/CSS/Test/CSS1/19990126/sec5526c.htm CSS1 Test Suite: 5.5.26 clear] ] . Acid1 is included as an offline easter egg, accessible by typing 'about:tasman', in Internet Explorer 5 for Mac OS with the text replaced with the names of the developers.

Acid1 has served as inspiration for Acid2 and Acid3.
