You can either use CSS media queries, like so:
<link rel="stylesheet" media="screen and (min-device-width: 700px)" href="https://stackoverflow.com/questions/11962837/css/narrow.css" />
<link rel="stylesheet" media="screen and (min-width: 701px) and (max-width: 900px)" href="css/medium.css" />
<link rel="stylesheet" media="screen and (max-device-width: 901px)" href="css/wide.css" />
Or jQuery, like so:
function adjustStyle(width) {
width = parseInt(width);
if (width < 701) {
$("#size-stylesheet").attr("href", "https://stackoverflow.com/questions/11962837/css/narrow.css");
} else if ((width >= 701) && (width < 900)) {
$("#size-stylesheet").attr("href", "css/medium.css");
} else {
$("#size-stylesheet").attr("href", "css/wide.css");
}
}
$(function() {
adjustStyle($(this).width());
$(window).resize(function() {
adjustStyle($(this).width());
});
});
