[Cropping an image proportionally with css.]
Damnit -- the object-fit property doesn't work in IE (not even 11!!!) so the image ends up distorted :(
.imagewrapper {
overflow: hidden;
// padding-top is the ratio of your design image's height/width
padding-top: 64.5%;
position: relative;
width: 100% // or however wide you want your cropped image to be
img {
bottom: 0;
height: 100%;
left: 0;
object-fit: cover;
position: absolute;
right: 0;
top: 0;
width: 100%;
}
}
