Hi @shrinet,
thank you for your contribution!

Could you please check the code review recommendations?

I guess we may also revert the fixes provided by PR #20168, don't we?

Thank you!

It would be better to use .lib-inline-block-space-container() and .lib-inline-block-space-item() mixins for this purpose.
Please check lib/web/css/source/lib/_utilities.less:252 for more details.
