Round Corners for Gmail Newsletter

i am trying to apply开发者_如何学C a rounded corner style for a newsletter i made, when i open the file locally everything seems fine, but when sent to a gmail account, it will strip some codes and wont read some inline css properties.

So my question is, if there is a way to create round corner, while not making it look bad for the other mail clients.

Thanks.

CSS is less supported in email newsletters. It is better to use image slices for the best results.
