CSS properity #1701

Closed prithiviclteam closed 3 years ago

prithiviclteam commented 3 years ago

Hi Team,

We have using unicode-bidi:bidi-override; this properity in CSS its showing below error.

ERROR(CSS-001): 95156_EPUB.epub/EPUB/styles/styles.css(1649,1): The "unicode-bidi" property must not be included in an EPUB Style Sheet.

Please check and advice how to handle this type of CSS, we are using Fixed layout epub for alignment.

Thanks, Prithiviraj M

@prithiviyaso is this an error raised by epubcheck? A particular reading system?

iherman commented 3 years ago

In any case, the EPUB 3.2 specification is clear: the unicode-bidi property is disallowed:

A conformant CSS style sheet MUST meet all of the following criteria:

  • It MAY include any CSS properties, with the following exceptions:
    • It MUST NOT use the direction property [CSS-Writing-Modes-3]. Use the [HTML] dir attribute to set the inline base direction.
    • It MUST NOT use the unicode-bidi property [CSS-Writing-Modes-3]. Use [HTML] bdo elements and dir attributes to control bidirectionality.

The error message is therefore correct, wherever it comes from...

It show error using epubchecker,

It show error using epubchecker,

And, as I said in https://github.com/w3c/epub-specs/issues/1701#issuecomment-860755724, epubcheck is correct. Note that this restriction is also in place for the upcoming 3.3 version of EPUB.
