Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
The CSS Working Group has published an updated Working Draft of CSS Grid Layout Level 1. This CSS module defines a two-dimensional grid-based layout system optimized for user interface design.
There were lots of changes since the last Working Draft, including:
As resolved in May as part of the Logical Directions Renaming, we’ve updated the grid placement longhand properties to be
grid-column-end with the shorthands
grid-area. (We expect authors to use the shorthands most frequently.)
As discussed at the Tokyo F2F in June, we also renamed the
grid-definition-rows/columns properties to
grid-template-rows/columns, and changed
grid-template-areas. This gives all the properties defining the explicit grid the same prefix. (We also added a
grid-template shorthand, for good measure.)
We adopted the
grid shorthand syntax from the Template Layout module and added the ability to set values for auto-formatted grids. The template shorthand syntax allows authors to visually associate the various row and column measurements with their respective rows and columns in the named template areas.
The previous named lines syntax was pretty awkward, as pointed out in this thread. It also used strings as CSS-internal identifiers, which we don’t do anywhere else. We adopted the proposal from that thread, which was to switch to identifiers and use parentheses to group multiple names for the same position. This has the benefit of
A more subtle change to named lines is that named grid areas now implicitly create named lines corresponding to their start and end edges, so you can more easily position something to the start or end edge of a particular named grid area without having to explicitly name those lines.
We’ve also clarified how absolutely-positioned items interact with the grid-placement properties, defined the static position of grid container children, rewrote and fixed errors in auto-placement algorithm.
And last but not least, we redesigned the subgrids feature, which allows alignment across the contents of a grid container’s immediate children.
We still have some open issues, in particular some open discussion around the
grid-auto-flow, that we hope to resolve soon. After that we expect most of the high-level design work to be complete, and then we’ll be digging into the gnarly layout details until we iron them all out.
As always, please send feedback to the (archived) public mailing list firstname.lastname@example.org with the spec code (
[css-grid]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
