Agenda+ CSS actions review

Response to Elika's email of 4th October at https://lists.w3.org/Archives/Public/public-tt/2018Oct/0011.html


Do the updates to CSS Text address the requirements we put forward for presentation of subtitles and captions?


For reference, we have the following CSS issues open:

[css-sizing][css-align][css-text] Aligning an aligned block of text within its container <https://github.com/w3c/csswg-drafts/issues/1975> TTML<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3ATTML>css-align-4<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-align-4> css-sizing-4<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-sizing-4> css-text-4<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-text-4>
[css-inline] Allow background of an inline area to extend to before-and after-edges of the line area <https://github.com/w3c/csswg-drafts/issues/1974> TTML<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3ATTML> css-inline-3<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-inline-3>
[css-inline][css-text-4] Allow padding to be applied at line start and end <https://github.com/w3c/csswg-drafts/issues/1973> TTML<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3ATTML> css-inline-3<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-inline-3>css-text-4<https://github.com/w3c/csswg-drafts/issues?q=is%3Aissue+is%3Aopen+ttml+label%3Acss-text-4>
#2983 Support for shearing of lines and inline elements<https://github.com/w3c/csswg-drafts/issues/2983>

Additionally the following CSS issues may be of interest:

[css-fonts-4] oblique angle for synthesis in vertical text <https://github.com/w3c/csswg-drafts/issues/2869>  css-fonts-4<https://github.com/w3c/csswg-drafts/issues?q=is%3Aopen+label%3Acss-fonts-4>
[css-inline] Define the content area of inline boxes <https://github.com/w3c/csswg-drafts/issues/814> css-inline-3<https://github.com/w3c/csswg-drafts/issues?q=is%3Aopen+is%3Aissue+label%3Acss-inline-3>

Are CSS issues filed for all style attributes for which we believe CSS work is needed?
