Fancy Media Queries with some LESS Magic

Question

It would be nice to wrap css-styles for different resolutions within some css-classes using less.

I\'d like to do something like:

footer {
  width: 1         


        

Answer 1

I am using these mixins & variables

.max(@max; @rules){@media only screen and (max-width: (@max - 1)){@rules();}}
.min(@min; @rules){@media only screen and (min-width: @min){@rules();}}
.bw(@min; @max; @rules){@media only screen and (min-width: @min) and (max-width: (@max - 1)){@rules();}}

@pad: 480px;
@tab: 800px;
@desktop: 992px;
@hd: 1200px;

So this

footer{
    width: 100%;
    .bw(@tab,@desktop,{
        width: 768px;
    });
    .min(@desktop,{
        width: 940px;
    });
}

becomes

footer {
  width: 100%;
}
@media only screen and (min-width: 800px) and (max-width: 991px) {
  footer {
    width: 768px;
  }
}
@media only screen and (min-width: 992px) {
  footer {
    width: 940px;
  }
}
