@media rule

The @media rule allows set style depending from media type and its features. There are CSS libraries like Bootstrap 5 that make this kind of work easier.

<link rel="stylesheet" media="screen and (min-width: 900px)" href="/css/widescreen.css">
<link rel="stylesheet" media="screen and (max-width: 320px)" href="/css/smallscreen.css">

@media print {
  body { font-size: 10pt; }

@media screen {  
  body { font-size: 13px; } 

@media screen, print {
  body { line-height: 1.2; }

@media screen 
  and (min-width: 320px) 
  and (max-width: 480px)
  and (resolution: 150dpi) {
    body { line-height: 1.4; }
<!-- media query lvl 4 -->
@media (height > 600px) {
    body { line-height: 1.4; }

@media (400px <= width <= 700px) {
    body { line-height: 1.4; }

Media Queries 4:

  1. The logical operators not, and and or can be used to compose a complex media query. Comma can be used as or operator. Keyword only is deprecated.
  2. You can use improved syntax for define range of value via relational operators.

media types

Only followed types are allowed in Media Queries 4. And types like tv now are deprecated.
