# Breaking: #92678 - CSS class checkbox-invert removed {#breaking-92678}

See [forge#92678](https://forge.typo3.org/issues/92678)

## Description {#description}

FormEngine used to have a class `checkbox-invert` for the styling
of an item with enabled flag `invertStateDisplay`. Now the checkbox value
itself is inverted. Therefore the class has been removed as it is not needed
any more.

## Impact {#impact}

Using the class doesn't have any effect on styling anymore.

## Affected Installations {#affected-installations}

Standard installations of TYPO3 are not affected. Only installations that
use the class `checkbox-invert` for customizations are affected.

## Migration {#migration}

There is no migration required if only the invertStateDisplay configuration
is used. If CSS styling or JavaScript in the backend relies on the
class `checkbox-invert` present custom code needs to be added to make it
available again.
