@media

Min Width to Max Width

You can also use the values to set a minimum width and a maximum width.

For example, when the browser’s width is between 600 and 900px, change the
appearance of a <div> element:

Example

@media screen and (max-width: 900px) and (min-width: 600px) {  div.example {
font-size: 50px;    padding: 50px;
border: 8px solid black;    background: yellow; }}

Using an additional value: In the example below, we add an additional media query to our already
existing one using a comma (this will behave like an OR operator):

Example

/* When the width is between 600px and 900px OR above 1100px
— change the appearance of <div> */@media screen and (max-width: 900px) and (min-width:
600px), (min-width:
1100px) {  div.example {
font-size: 50px;    padding: 50px;
border: 8px solid black;    background: yellow; }}

Definition and Usage

The rule is used in media queries to apply different styles for different media types/devices.

Media queries can be used to check many things, such as:

width and height of the viewport
width and height of the device
orientation (is the tablet/phone in landscape or portrait mode?)
resolution

Using media queries are a popular technique for delivering a tailored style
sheet (responsive web design) to desktops, laptops, tablets, and mobile phones.

You can also use media queries to specify that certain styles are only for printed documents or for screen readers (mediatype: print, screen, or speech).

In addition to media types, there are also media features. Media features
provide more specific details to media queries, by allowing to test for a
specific feature of the user agent or display device. For example, you
can apply styles to only those screens that are greater, or smaller, than a
certain width.

CSS Syntax

@media not|only mediatype and (mediafeature and|or|not
mediafeature) { CSS-Code;}

meaning of the not, only and and keywords:

not: The not keyword inverts the meaning of an entire media
query.

only: The only keyword prevents older browsers that do not support media queries with media features from applying the specified styles.
It has no effect on modern browsers.

and: The and keyword combines a media feature with a media
type or other media features.

They are all optional. However, if you use not or
only, you must also specify a media type.

You can also have different stylesheets for different media, like
this:

Typical Device Breakpoints

There are tons of screens and devices with different heights and widths, so it is hard to create an exact breakpoint for each device. To keep things simple you could target
five groups:

Example

/*
Extra small devices (phones, 600px and down) */@media only screen and (max-width: 600px)
{…} /* Small devices (portrait tablets and large phones, 600px and up)
*/@media only screen and (min-width: 600px) {…} /* Medium devices (landscape tablets, 768px and up) */
@media only screen and (min-width: 768px) {…} /* Large devices (laptops/desktops, 992px and up)
*/
@media only screen and (min-width: 992px) {…} /* Extra large devices (large
laptops and desktops,
1200px and up) */@media only screen and (min-width: 1200px) {…}

Media Queries For Columns

A common use of media queries, is to create a flexible layout. In this example, we create a layout that varies between four, two and full-width columns, depending on different screen sizes:

Large screens:

Medium screens:

Small screens:

Example

/* Create four equal columns that floats next to each other */.column {
float: left; width: 25%;}/* On screens that are 992px
wide or less, go from
four columns to two columns */@media screen and (max-width: 992px) {
.column { width: 50%; }}/* On screens that are
600px wide or less, make
the columns stack on top of each other instead of next to each other */
@media screen and (max-width: 600px) { .column { width:
100%; }}

Tip: A more modern way of creating column layouts, is to use CSS Flexbox (see example below).
However, it is not supported in Internet Explorer 10 and earlier versions. If you require IE6-10 support, use floats (as shown above).

To learn more about the Flexible Box Layout Module, read our CSS Flexbox chapter.

To learn more about Responsive Web Design, read our Responsive Web Design Tutorial.

Example

/* Container for flexboxes */.row { display: flex;
flex-wrap: wrap;}/* Create four equal columns */.column { flex: 25%;
padding: 20px;}/* On screens that are 992px wide or less, go from
four columns to two columns */@media screen and (max-width: 992px) {
.column { flex: 50%; }}/* On screens that are 600px wide or less, make
the columns stack on top of each other instead of next to each other */
@media screen and (max-width: 600px) { .row {
flex-direction: column; }}

Another Breakpoint

You can add as many breakpoints as you like.

We will also insert a breakpoint between tablets and mobile phones.

Desktop

Tablet

Phone

We do this by adding one more media query (at 600px), and a set of new classes for devices larger than 600px
(but smaller than 768px):

Example

Note that the two sets of classes are almost identical, the only
difference is the name ( and ):

/* For mobile phones: */ { width: 100%;}@media only screen and (min-width: 600px) {

/* For tablets: */ .col-s-1 {width: 8.33%;} .col-s-2 {width: 16.66%;}
.col-s-3 {width: 25%;} .col-s-4 {width: 33.33%;} .col-s-5 {width: 41.66%;}
.col-s-6 {width: 50%;} .col-s-7 {width: 58.33%;} .col-s-8 {width: 66.66%;}
.col-s-9 {width: 75%;} .col-s-10 {width: 83.33%;} .col-s-11 {width: 91.66%;}
.col-s-12 {width: 100%;}}@media only screen and (min-width:
768px) { /* For desktop: */ .col-1 {width: 8.33%;} .col-2 {width: 16.66%;}
.col-3 {width: 25%;} .col-4 {width: 33.33%;} .col-5 {width: 41.66%;}
.col-6 {width: 50%;} .col-7 {width: 58.33%;} .col-8 {width: 66.66%;}
.col-9 {width: 75%;} .col-10 {width: 83.33%;} .col-11 {width: 91.66%;}
.col-12 {width: 100%;}}

It might seem odd that we have two sets of identical classes, but it gives us the
opportunity in HTML, to decide what will happen with the columns at each
breakpoint:

HTML Example

For desktop:

The first and the third section will both span 3 columns each. The middle section will span 6 columns.

For tablets:

The first section will span 3 columns, the second will span 9, and the third section will be displayed below the first two sections, and it will span 12 columns:

Media Queries For Columns

A common use of media queries, is to create a flexible layout. In this example, we create a layout that varies between four, two and full-width columns, depending on different screen sizes:

Large screens:

Medium screens:

Small screens:

Example

To learn more about the Flexible Box Layout Module, read our CSS Flexbox chapter.

Example

Media Query Syntax

A media query consists of a media type and can contain one or more
expressions, which resolve to either true or false.

@media not|only mediatype and (expressions) { CSS-Code;}

The result of the query is
true if the specified media type matches the type of device the document is
being displayed on and all expressions in the media query are true. When a media query is true, the corresponding style sheet or style rules are
applied, following the normal cascading rules.

Unless you use the not or only operators, the media type is optional and the
type will be implied.

You can also have different stylesheets for different media:

More Examples

Example

Hide an element when the browser’s width is 600px wide or less:

@media screen and (max-width: 600px) { div.example { display:
none;
}}

Example

Use mediaqueries to set the background-color to lavender if the viewport is
800 pixels wide or wider, to lightgreen if the viewport is between 400 and 799 pixels wide.
If the viewport is smaller than 400 pixels, the background-color is lightblue:

body {  background-color: lightblue;}@media screen and (min-width:
400px) { body {
background-color: lightgreen;  }}@media
screen and (min-width: 800px) { body {
background-color: lavender; }}

Example

Create a responsive navigation menu (displayed horizontally on large screens and vertically on small screens):

@media screen and (max-width: 600px) { .topnav a {
float: none; width: 100%;
}}

Example

Use media queries to create a responsive column layout:

/* On screens that are 992px wide or less, go from four columns to two
columns */@media screen and (max-width: 992px) { .column {
width: 50%;  }}/* On screens that are 600px wide or less, make the columns stack
on top of each other instead of next to each other */@media screen and (max-width:
600px) {  .column {    width: 100%;
  }}

Example

Use media queries to create a responsive website:

Example

Media queries can also be used to change layout of a page depending on the
orientation of the browser. You can have a set of CSS properties that will only
apply when the browser window is wider than its height, a so called «Landscape»
orientation.

Use a lightblue background color if the orientation is in landscape mode:

@media only screen and (orientation:
landscape) {  body {

background-color: lightblue;  }}

Example

Use mediaqueries to set the text color to green when the document is
displayed on the screen, and to black when it is printed:

@media screen { body {
color: green;   }}@media print {  body {    color: black;
  }}

Example

Comma separated list: add an additional media query to an already existing one, using a comma (this will behave like an OR operator):

/* When the width is between 600px and 900px OR above 1100px — change the
appearance of <div> */@media screen and (max-width: 900px) and
(min-width: 600px), (min-width: 1100px) { div.example {
font-size: 50px;    padding: 50px;
border: 8px solid black;    background: yellow;
}}

CSS Media Queries — More Examples

Let us look at some more examples of using media queries.

Media queries are a popular technique for delivering a tailored style sheet to different devices. To demonstrate a simple example, we can change the background color for different devices:

Example

/* Set the background color of body to tan */body {
background-color: tan;}/* On
screens that are 992px or less, set the background color to blue */@media
screen and (max-width: 992px) { body {
background-color: blue; }}/* On screens that are 600px or less,
set the
background color to olive */@media screen and (max-width: 600px) {
body { background-color: olive; }}

Do you wonder why we use exactly 992px and 600px? They are what we call «typical breakpoints» for devices. You can read more about typical breakpoints in our Responsive Web Design Tutorial.

Что такое медиа-запрос?

Медиа-запрос — это способ контролировать представление контента. Он состоит из типа и минимум одного выражения, которое проверяет выполнение условий для указанных характеристик устройства.

Как уже было сказано, в настоящее время широко реализована поддержка двух типов: «screen» и «print«.

При наличии условных выражений контент может выводиться по-разному для различных типов устройств, без ущерба для содержимого.

Как определить медиа-запрос?

Простой медиа-запрос может быть определен в HTML следующим образом:

<link rel="stylesheet" media="print" href="myexample.css" />

В приведенном выше примере, мы указали, что для типа медиа «print» браузер пользователя должен использовать таблицу стилей myexample.css.

То же самое может быть объявлено как @import-правило в CSS:

@import url(myexample.css) print;

Когда браузер пользователя обрабатывает приведенный выше медиа-запрос, он определяет, текущий тип медиа — print или нет. Если да, то будет применяться таблица стилей «myexample.css«. Следовательно, вывод медиа-запросов можно организовать в зависимости от выполняемых условий.

Если тип устройств не задан или задано значение ‘all‘, то стили будут применяться для всех типов медиа.

Например:

<link rel="stylesheet" href="myexample.css" />
<link rel="stylesheet" media="all" href="myexample.css" />

В приведенном выше примере, стили будет применяться как для типа ‘print‘, так и для типа ‘screen‘. Это эквивалентные объявления. Как и следующий CSS-код:

@media all { … }
@media { … }

Медиа-запросы могут быть объединены в сложные медиа-запросы:

<link rel="stylesheet" media="print, projection" href="myexample.css" />

Этот запрос также может быть объявлен следующим образом:

@media print, projection { … }

Медиа-запросы также поддерживают логическое выражение NOT, используя ключевое слово «NOT«:

<link rel="stylesheet" media="not print, screen" href="myexample.css" />

В приведенном выше примере мы указали, что стили не будут применяться к типу ‘print‘, а только к типу ‘screen‘.
