The @media at-rule specifies a set of styles that are applied only to certain media types.
Media queries are a popular technique for delivering a responsive web design to desktops, laptops, tablets, and mobile phones.
Besides media types, there are media features which have names and accept certain values like properties. But there are differences between properties and media features:
- Properties cannot display without values, and features do not require values.
- Features accept only single value unlike properties.
Media queries are used to check the following:
- width and height of the viewport
- width and height of the device
- orientation
- resolution
In JavaScript, the CSSMediaRule interface which represents a single @media rule can access the rules created with @media.
Initial Value | all |
Applies to | Certain media types. |
Inherited | No. |
Animatable | Yes. |
Version | Media Queries, CSS2 |
DOM Syntax | object.style.@media = "screen and (min-width: 500px)"; |
Syntax
@media: media-type (and media-query-feature);
Example of the @media rule:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<style>
body {
background-color: #1c87c9;
}
@media screen and (max-width: 411px) {
body {
background-color: #cce5ff;
}
}
@media screen and (min-width: 768px) {
body {
background-color: #eee;
}
}
@media screen and (max-width: 962px) and (min-width: 450px),
(min-width: 1366px) {
background-color: #333;
}
</style>
</head>
<body>
<h2>@media rule example</h2>
<p>Resize the browser to see the effect.</p>
<p>Media queries set the background-color to light gray if the viewport is 600 pixels wide or wider, to green if the viewport is between 200 and 599 pixels wide. If the viewport is smaller than 200 pixels, the background-color is blue.</p>
</body>
</html>
Result
In the following example, when the browser's width is between 500 and 800px or above 1000px, the appearance of <div> changes. Resize the browser window to see the effect.
Example of the @media rule with a changed appearance of <div>:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<style>
body {
background-color: #1c87c9;
}
@media screen and (min-width: 200px) {
body {
background-color: #8ebf42;
}
}
@media screen and (min-width: 600px) {
body {
background-color: #ccc;
}
}
@media screen and (max-width: 800px) and (min-width: 500px),
(min-width: 1000px) {
div.box {
font-size: 50px;
padding: 50px;
border: 8px solid #000;
background: #eee;
}
}
</style>
</head>
<body>

Example of using media for hiding an element on extra small devices:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
<style>
@media (max-width: 767px) {
.hide-mobile {
display: none;
}
}
</style>
</head>
<body>
<h1>Hi</h1>
<p>There is some text for example.</p>
<p class="hide-mobile">This text will be hidden on large devices.</p>
<p>There is some text for example.</p>
</body>
</html>
Example of using media for changing the content background color on different devices.
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<style>
@media screen and (max-width: 767px) {
.content {
background-color: lightblue;
padding: 30px;
}
}
@media screen and (min-width: 768px) {
.content {
background-color: pink;
padding: 10px;
}
}
@media screen and (min-width: 800px) {
.content {
background-color: lightgreen;
color: white;
padding: 50px;
}
}
</style>
</head>
<body>
<div class="content">
<h2>Resize the browser to see the effect.</h2>

CSS is a rule-based language, which means that you define
rules specifying groups of styles applying to particular
elements or groups of elements on the web page.
