1432148 - [css-align] 'overflow' keyword must precede the self-position and content-position value

Status: RESOLVED DUPLICATE of bug 1430817

(Core :: CSS Parsing and Computation, defect, P3)

Description

[Javier Fernandez]

Attachment: Test case to reproduce the bug

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20180104112904

Steps to reproduce:

1- Load the attached test case


Actual results:

Once the test case is loaded it'll show the specified and computed values for align-self, align-items and align-content CSS properties and the values that they should shown.

The three properties show incorrect specified and computed values


Expected results:

The loaded tests show that both specified and computed values match the expected one. 

This is the current syntax for the evaluated CSS properties:

https://drafts.csswg.org/css-align-3/#align-self-property
https://drafts.csswg.org/css-align-3/#align-items-property
https://drafts.csswg.org/css-align-3/#align-justify-content

See the CSS WG discussion about the syntax change:

There are Web Platform Tests to define and verify the behavior of these CSS Alignment properties:

 https://github.com/w3c/web-platform-tests/tree/master/css/css-align

It'd be great if any change or disagreement about this issue could eventually lead to an update of those tests, so that we can use them to detect and manage browser interoperability problems.

Yup, agreed.

Will take a look at this this week, thanks Javier!

This CSS WG discussion is perhaps more appropriated and specific for this bug:
