How to duplicate a colorbox on my website

hiya, please can you show me how to duplicate a colourbox (from my portfolio section, so that I can showcase more of my work). Thank you

Open the navigaotr tab, open the portfolio section, select the second portfolio row and cmd+c cmd+v to duplicate it. then select the last column of the second row and delete the last element that is used as a dummy to make the gap under the row (wich is a bad way to make a margin imho)
