Subject: [OASIS Issue Tracker] (OFFICE-3947) Wrong normative reference for attribute 20.349 style:shadow
[ https://issues.oasis-open.org/browse/OFFICE-3947?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=69318#comment-69318 ]
Regina Henschel commented on OFFICE-3947:
-----------------------------------------
I have sent a mail with an attachment to test, how browsers render boxes around text. http://markmail.org/message/jpaf3grp57jlvjko
The issue OFFICE-3843 proposes to add style:shadow to text:properties. Currently the attribute style:shadow is only used for objects, which do not have text around them, for example for a shadow around the header. Therefore this problem is new.
An HTML5 document, which uses the box-shadow CSS property to get borders around portion of text, is rendered by the browsers in a way, that the text goes to the edge of the border area. That way text and shadow overlap. Test it with the mentioned document from the mailing list.
Word and LibreOffice do not overlap text and shadow. To remove such overlapping in HTML the CSS property margin-left and margin-right can be used. We need to decide, whether rendering of shadows shall follow the way browsers do it (which means using CSS3 as reference), or whether we will specify an own way.

> The behavior of Word and LibreOffice is similar to the CSS property "box-shadow" https://www.w3.org/TR/2017/CR-css-backgrounds-3-20171017/#the-box-shadow.
> It seems, that even https://www.w3.org/TR/xslfo20/ does not have something similar. Unfortunately CSS 2 has it neither.
