bug

What is the current behavior?
creating a animation in :global scope animation's name is translated to local name in the keyframes

If the current behavior is a bug, please provide the steps to reproduce.

compiling this css:

:global {
    .shake {
        animation: example 3s linear;
    }
    @keyframes :global(example) {
        0%   {background-color: red;}
        100% {background-color: green;}
    }
}

results in (files name is _core)

.shake {
    animation: example 3s linear;
}
@-webkit-keyframes _core__-global-example- {
    0%   {background-color: red;}
    100% {background-color: green;}
}

What is the expected behavior?
should result in

.shake {
    animation: example 3s linear;
}
@-webkit-keyframes example {
    0%   {background-color: red;}
    100% {background-color: green;}
}

If this is a feature request, what is motivation or use case for changing the behavior?

Same problem here, did you find a workaround?

[wende60]

did something like

:global {
    .myclass {
        :local {
            animation: ...
        }
    }
}

so you have a global class and everything inside is local

Problem on postcss-modules side, we can't do anything here, sorry. Feel free to create issue in postcss-modules repo

[jahed]

The fix I found is to do:

:global {
    .shake {
        animation: example 3s linear;
    }
}

@keyframes :global(example) {
    0%   {background-color: red;}
    100% {background-color: green;}
}

In general, any @ rules in :global seems to cause incorrect behaviour. Not sure if it's part of CSS Modules spec to behave like that or not.

For reference, I found this issue while debugging and documented several approaches here: https://gravitydept.com/blog/keyframe-animations-in-css-modules
