Customize Portfolio

Hi there,

i have an issue with the portfolio item. I want to have 4 columns wich have no space between the elements. So I set the portfolio to full width and reduced the columns from 5 to 4.
So the layout of the page ist full width with a gap of 45px left and right.
On the left side the gap is visible even in the portfolio element, but on the right not.
Any ideas?
