Compatibility Master Table

Hell is other browsers — Sartre

This page has been translated into Romanian and Russian.

My Compatibility Tables are by far the most popular resource on this site. Here you find the master table that contains links to the individual tables.

A “To be tested” means that I haven’t yet tested the specific browser named in the table. Usually the detail table contains data about a previous version, though.

An “Untestable” means that I no longer have that browser available due to browser vendors’ absurd update policies that remove older versions without warning.

When I test new browsers I do not always run all the tests; doing so would cost me about a week of full-time work. Therefore most tables usually lag behind the latest crop of browsers. In general, when a new test round starts I test the table that’s most behind and work my way up to the more recently updated tables.

Load the update dates of the individual tables (may take a little while).

Current tests

DOM Events When do the various events fire in the desktop browsers?
HTML5 tests Tests of a few HTML5 features. Needs many more tests.

CSS 2
 Incorrect Incomplete Yes Yes Yes Yes Yes To be tested

CSS 2 has become the baseline of CSS support; without it a browser is decidedly backward.
CSS 3
 Minimal Incomplete Almost Almost Almost Almost Almost To be tested

The compatibility information here is about the CSS3 modules I test. It is not necessarily valid for the browsers’ entire CSS3 support.
DOM Core
Node manipulation 		Yes Yes Yes Yes Yes To be tested

The W3C DOM Core module defines how to access, read and manipulate an XML document. Well-formed HTML documents are XML documents, so these methods and properties can be used to completely rewrite any HTML page, if you so wish.

Here you find details on how to find elements, how to create new ones, how to read out node information and how to change the structure of the document.
DOM HTML
HTML tag manipulation 		Yes Yes Yes Yes Yes To be tested

Though HTML documents are XML documents, they have a number of special features that the average XML document doesn't have. The W3C DOM HTML module defines these special cases and how to deal with them.

Here you find details on getting and setting properties of HTML elements, such as className or id. The innerHTML property is of prime importance to any DOM script.
DOM CSS
Stylesheet manipulation 		Alternative Yes Yes Yes Yes Yes To be tested

Style sheets are part of the document, too (sort of). The W3C DOM CSS module gives access to style sheets and allows you to change a style sheet.

This module contains some browser incompatibilities, but they are of the cute kind. W3C and Microsoft define some different methods and arrays, but some simple object detection allows you to evade these problems.
CSS Object Model View
Element dimensions, mouse coordinates, and miscellaneous 		Incomplete Almost Yes Almost Almost Almost Almost To be tested

This specification contains several age-old properties that all browser support but that never have made it to a W3C specification yet.

In addition to the tables mentioned above I created the following resources that are unfortunately out-of-date. Use with care:
