Notes from previous discussions etc:

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:

w3c/csswg-drafts#1975 [css-sizing][css-align][css-text] Aligning an aligned block of text within its container
w3c/csswg-drafts#1974 [css-inline] Allow background of an inline area to extend to before-and after-edges of the line area
w3c/csswg-drafts#1973 [css-inline][css-text-4] Allow padding to be applied at line start and end
w3c/csswg-drafts#2983 Support for shearing of lines and inline elements

Additionally the following CSS issues may be of interest:

w3c/csswg-drafts#2869 [css-fonts-4] oblique angle for synthesis in vertical text
w3c/csswg-drafts#814 [css-inline] Define the content area of inline boxes

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