This page summarises results for a series of tests that seek to establish how browsers support the CSS direction and unicode-bidi properties for HTML and XHTML. These properties are used to control inline direction of text.
Note that CSS properties are not needed for documents served as HTML; the HTML markup should suffice. This is also the case for XHTML served as XML. They are needed, however, for other documents served as XML.
See the results below for user agents tested. This section summarizes the results of those tests. In what follows, 'HTML' means HTML4.01 or XHTML 1.0 served as text/html. XML means XHTML 1.0 or XHTML 1.1 served as application/xhtml+xml.
All user agents passed all tests, with two minor exceptions in two browsers.
The exceptions were that if an override was applied to a block element containing a child block element followed by inline text, neither Safari nor Chrome (both WebKit based) applied the override to the inline text.
These are results for the latest versions of each user agent tested. A green background (yes) means that the assertion associated with the test held true; red (no) means that it did not; orange (partially) means that it was only partially true. To view the assertion, click on test title (left-most column) to see the assertion on a sample test.
Results are given for four types of document format: H4 (HTML 4.01), XH (XHTML 1.0 served as text/html), X (XHTML 1.0 served as XML), X11 (XHTML 1.1, served as XML), but since all result were the same for the browsers tested, a single cell is used to represent all four test instances. Internet Explorer doesn't handle pages served as XML, so those tests are ignored in these results.
