Issue with spacing between columns in firefox

[techexplorer]

I am working on a 4 column layout using 1 column as a spacer between the two right columns. This works fine in IE and shows the 10px space between columns, but in firefox my columns are right next to each other. Any ideas? Thanks!

Why use columns as "spacer" to start with ? Margins and padding exist for that purpose ...

might be collapsing margins that you see, a lot depends on the code you have (and BTW: whenever IE and FF disagree how to render something the odds are 100:1 that firefox is right ...)

Some minimal examplified code that exhibits the problem could be posted and then we can try to understand what the problem is.

Thanks for the info. using padding fixed the problem and I removed the spacing column. I'm new at css as I'm sure you noticed.
