[dated info] by percent of layout engines/web browsers
The following tables compare general and technical information for a number of layout engines. While these are mainly used in web browsers, they are also used in email clients for rendering HTML email, and used to render EPUB e-books, for example. This article is not all-inclusive or necessarily up to date—please see individual "Comparison of layout engine" articles for detailed comparisons of HTML5 feature support, CSS feature support, and the like. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.
