Hi kim minseok,
From your update we suspect that you are using an old
version of CSS. We recommend updating the CSS to the latest version in the
index.html file since we made some feature improvement changes from Volume 3
release. Please refer to the code snippet for guidance.
If you are still facing the issue, please share the full
Grid code example, style reference code and a issue replicable sample which
will be helpful for us to validate further.
Regards,
Pavithra S
