In an attempt to remove the color from the column border following a click on the image, I am struggling to locate the specific code segment that needs adjustment. I have scrolled through the entire code and experimented with color changes without success. Your guidance would be greatly appreciated.
body {font-family: 'Roboto', sans-serif; overflow-x:hidden}
#portfolio .portfolio-item {margin:0 0 15px; right:0}
