Adjust WPT percentage-heights-013.html to explicitly style its unrecognized-embed as a box that accepts CSS 'height'. Browsers aren't currently interoperable on what the fallback rendering is for embed elements with unrecognized 'type' attributes. Firefox renders them as an empty inline element (like an empty 'span'), whereas other browsers render them as a fallback graphic with the 300x150 default replaced-element size. We should probably try to achieve interop on this embed fallback behavior, but it's not relevant to what this test is testing, which is whether percentage heights can be resolved on children-of-flex-items. Percentages in fact *do* resolve properly here, in all browsers. But the last subtest is failing in Firefox before this patch, simply because we're treating the embed as an empty inline element -- and consequently, we're ignoring its 'height' property entirely, just like we do on e.g. inline-level 'span'. This patch avoids tripping over this 'embed' fallback-behavior behavioral difference by forcing the embed element to be 'display: inline-block', which makes its height property be recognized and honored, so that we can validate that the percentage resovles.

The web-platform-tests Project is a cross-browser test suite for the Web-platform stack. Writing tests in a way that allows them to be run in all browsers gives browser projects confidence that they are shipping software that is compatible with other implementations, and that later implementations will be compatible with their implementations. This in turn gives Web authors/developers confidence that they can actually rely on the Web platform to deliver on the promise of working across browsers and devices without needing extra layers of abstraction to paper over the gaps left by specification editors and implementors.
The most important sources of information and activity are:
wpt:matrix.org
matrix channel; includes participants located around the world, but busiest during the European working day.If you'd like clarification about anything, don't hesitate to ask in the chat room or on the mailing list.

Note: because of the frequent creation and deletion of branches in this repo, it is recommended to “prune” stale branches when fetching updates, i.e. use git pull --prune
(or git fetch -p && git merge
).
See the documentation website and in particular the system setup for running tests locally.
The wpt
command provides a frontend to a variety of tools for working with and running web-platform-tests. Some of the most useful commands are:
wpt serve
- For starting the wpt http serverwpt run
- For running tests in a browserwpt lint
- For running the lint against all testswpt manifest
- For updating or generating a MANIFEST.json
test manifestwpt install
- For installing the latest release of a browser or webdriver server on the local machine.wpt serve-wave
- For starting the wpt http server and the WAVE test runner. For more details on how to use the WAVE test runner see the documentation.On Windows wpt
commands must be prefixed with python
or the path to the python binary (if python
is not in your %PATH%
).
python wpt [command]
Alternatively, you may also use Bash on Ubuntu on Windows in the Windows 10 Anniversary Update build, then access your windows partition from there to launch wpt
commands.
Please make sure git and your text editor do not automatically convert line endings, as it will cause lint errors. For git, please set git config core.autocrlf false
in your working tree.
The master branch is automatically synced to wpt.live and w3c-test.org.
Save the Web, Write Some Tests!
Absolutely everyone is welcome to contribute to test development. No test is too small or too simple, especially if it corresponds to something for which you've noted an interoperability bug in a browser.
The way to contribute is just as usual:
git checkout -b topic
../wpt lint
as described above.If you spot an issue with a test and are not comfortable providing a pull request per above to fix it, please file a new issue. Thank you!
