I'm attempting to find where the inline style for containers is being applied when in admin mode.  I do not want the border.  With precise designs, such as columns of fixed width floating (e.g. three 200px wide div's floated left inside a 600px parent div), the additional 2 pixels to the width of the container makes these containers wrap, giving a skewed perception of the page's layout which is quite confusing to my clients.  Since this is an inline style, there is no possible way to override it via css.

I have searched the entire solution for the hex color of the border (#CCCCCC) in an attempt to find where this border is being added with no luck.  I have tried searching the entire solution for the application of a dotted border, period, with no luck.

Does anyone have any idea where this border is being added?  Is it being added in some compiled DLL?  I am aware that DNN 5 will have solved this issue, but that doesn't help the present.

That does the trick!  Timo, thank you very much.  Still curious to know where this is being applied just so I don't feel defeated.  I've searched everywhere aside from DLL source and can't find a thing!

Thanks, again.
