LESS: concatenate multiple background rules
I have a mixin that creates a gradient with vendors' prefixes, and I would like to add this background to a DIV in addition to another background-image . .horizontal(@start-color: #555; @end-color: #333; @start-percent: 0%; @end-percent: 100%) { background:@start-color; background-image: -webkit-linear-gradient(left, @start-color @start-percent, @end-color @end-percent); background-image: -o-linear-gradient(left, @start-color @start-percent, @end-color @end-percent); background-image+: linear-gradient(to right, @start-color @start-percent, @end-color @end-percent); background-repeat: repeat-x;
