By adding to what @brianMaltzan wrote about @media, you can use different permission groups to have a different stylesheet
<link rel='stylesheet' media='(max-width: 700px)' href='css/small.css' />
<link rel='stylesheet' media='(min-width: 701px) and (max-width: 1024px)' href='css/medium.css' />
<link rel='stylesheet' media='(min-width: 1025px)' href='css/large.css' />
or css code block to style your page:
@media (max-width: 860px) {
body {
width: 600px;
}
}
@media (min-width: 861px) and (max-width: 1024px) {
body {
width: 800px;
}
}
@media (min-width: 1025px) {
body {
width: 1000px;
}
}
