The following tables compare support of HTML5 differences from HTML for a number of layout engines.
Contents
Engine nomenclature
Rather than the names of web browsers and HTML to PDF converters, the names of the underlying engines are used. Some of the software and online converters that use the various engines are listed below.
Values
Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.
Elements
While many of these elements have not been implemented natively in layout engines, support can usually be emulated by web page authors using CSS or JavaScript.
Form elements and attributes
Many of these features can be emulated with third-party libraries.
Next-generation additions
The WHATWG version of HTML also includes additional features that are not technically HTML5, which are described as "next-generation additions still in development" in the specification.
