I'm working on the "Front-end Web Development" track and we've gotten to the point where we are organizing our photo gallery into two columns to fit a mobile device. In the training video, Nick minimizes his window as far as it will go and the pictures fit nicely (there are two pictures in the first two rows and one picture in the third row. When I try it, I almost get my window completely minimized, however, right at the last moment, the "number 6" image in the second row gets pushed to the right, forcing the "number 9" image down to the third row. So now, I have two images in the first row, one in the second, and two in the third. I noticed that the gray text area under the "number 1" image is longer than other ones. I'm using all of the same measurements that Nick is using (at least I think after double and triple checking). What could be causing this to happen? Thank you.
