• The addition of 'flex-1' on the parent container seems to fix the expansion issue, but please ensure that it does not introduce layout issues in other contexts. Consider adding a brief inline comment to explain its necessity.

• Including both 'w-1/2' and 'flex-1' on the child container ensures balanced sizing while allowing vertical expansion; please verify that this combination aligns with the overall responsive design strategy.
