Take a look at this https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries.

Another way is to attach the resize event some piece of "switch code".

Hey :D

CSS

.limit400 h1 { font-size:10px; }
.limit1200 h1 { font-size:50px; }

JS

$(window).on('resize', function() {
    if($(window).height() > 400) {
        $('#body').addClass('limit1200');
        $('#body').removeClass('limit400');
    }else{
        $('#body').addClass('limit400');
        $('#body').removeClass('limit1200');
    }
})
