Is it ok to use negative margins for positioning? I have a lot in my current site and feel like it\'s not such a stable way to position things. I usually suggest to use them
Negative margins have been known to cause problems in IE7 and below with content being cut off. And, as alias suggests, it could also indicate a problem with the rest of the design. But I think it is wrong to say that negative margins are 'bad development' in all cases. But as always, test test test.
