Typo in Docs - CSS > Using Less > Retina Images

[adamgruber]

In the Retina Images section, the example defines the mixin as:

.img-retina(@file-1x; @file-2x; @width-1x; @height-1x) {
  background-image: url("@{file-1x}");
...

but the usage is shown as

// Usage
.jumbotron {
  .retina-image("/img/bg-1x.png", "/img/bg-2x.png", 100px, 100px);
}

It should be .img-retina to match the name of the mixin.
