Featured-grid-Content rounded corners

Hi Sakin, One more question for you and I'll be good to go. I'm trying to add an border-radius to the featured-grid-content as follows: 1) 25px border-radius to the left top and left bottom corners of the grid-box.first (larger image in the grid) image 2) 25px border-radius to the right top of the 2nd image 3) 25px border-radius to the right bottom of the 3rd image. This would also need to be applied to the box-shadow as well when you hover over those images. Any easy way to change that styling? Thanks, Justin
