* exclude `Features.LogicalProperties` lightningcss feature
We don't want this to automatically apply since we have dedicated
logical property based utilities already.
We also have a feature flag to toggle some utilities to make use of
logical property based ones.
This feature should be opt-in to prevent backwards compatibility (e.g.:
RTL sites that _did_ use a mr-4 explicitly).
* update default browserslist
* explicitly include/exclude Lightning CSS features
* update tests based on new browserslist and include/exclude features from Lightning CSS
* update integration tests
* prefer user browserslist, fallback to built-in browserslist
* always include Nesting
If a custom browserslist config is used, then we don't explicitly set
the include/exclude features from Lightning CSS (except for nesting, we
always want to process nesting)
* ensure to fallback to the current working directory
* update changelog
* bump `lightningcss`
* allow for non-standard selector combinators such as `::deep`
* just use Prettier when comparing CSS results
We were using 2 different engines where the stable one was not using
Lightning CSS and the Oxide one was using Lightning CSS.
To ensure that we didn't have to rewrite every single test expectation,
the `toMatchFormattedCss` parsed both the actual and expected value
using Lightning CSS (to make the result similar), then it used Prettier
to make it... pretty.
Right now we _only_ use Lightning CSS, which means that we can drop the
additional lightningcss format step and just use Prettier on both the
actual and expected values.
Pretty also only prettifies the CSS, it doesn't rewrite it. E.g.:
`@media (min-width: 768px)` will not be optimized to `@media (width >=
768px)`, that's something that Lightning CSS does for us.
This will require some changes in our test output, but it will be
consistent afterwards because there won't be hidden transformation steps
anymore. Because up until now it could be that the actual result was
`color: black` but the tests showed `color: #000` (because it is
shorter).
This change will reflect reality.
* update tests based on previous commit
* only use `toMatchFormattedCss` instead of `toMatchCss`
They both do the exact same thing right now. While `toMatchCss` is
shorter, `toMatchFormattedCss` makes a bit more sense since we are
comparing the Prettier results.
* update integration tests
* drop empty lines when diffing output
* replace expected css with optimized lightningcss output
Lightning CSS generates a more optimal CSS output.
Right now the tests are setup in a way that both the generated css and
expected css are run through `lightningcss` to make sure that the output
is concistent for the `stable` and `oxide` engines. But this also means
that the expected output _could_ be larger (aka not optimized) and still
matches (after it runs through lightningcss).
By replacing this with the more optimal output we achieve a few things:
1. This better reflects reality since we will be using `lightningcss`.
2. This gets rid of unnecessary css.
3. Removed code!
