问题 I have been trying to "cut" an image for some time now, I ll explain why and what I tried. So I wanted to create an hp "bar" except it's not a bar but a heart and so I though it would be easy all I had to do is have two pictures draw them on top of each other and then just cut one to make it appear as in hp was being lost, but I was not able to find a way to cut the image.

问题 I've created a two-column grid of images, which works fine with all-landscape images: Link. However, I've added a portrait image that throws off the layout, so I'd like to be able to "crop" the image so that the height matches the others'.
