Tasman is a discontinued
layout engine developed by
Microsoft for inclusion in the Macintosh version of Internet Explorer 5. Tasman was an attempt to improve support for web standards, as defined by the
World Wide Web Consortium. At the time of its release, Tasman was seen as the layout engine with the best support for web standards such as
HTML and
CSS. Internet Explorer for Mac is no longer supported, but newer versions of Tasman are incorporated in some other Microsoft products.
