Negative Top Margin Leaves Blank Space On Background Image

scott74

I have a Negative Margin of 15 px on my slider to bring it up a little but when I do that it leave a blank space where the slider image is for the amount i added for the negative margin... Is there a fix for this?

Was the margin bottom from the column code and then the negative from the slider conflicting i guess..

Got rid of the negative from the slider and lessened the bottom margin on the column code..

.less-margin .column{

margin: 0 1% 15px!important;

}
