More Examples

Example

Css-свойство border

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;
}}

Media Queries Simple Examples

Display в css

One way to use media queries is to have an alternate CSS section right inside your style sheet.

The following example changes the background-color to lightgreen if the
viewport is 480 pixels wide or wider (if the viewport is less than
480 pixels, the background-color will be pink):

Example

@media screen and (min-width: 480px) { body {
background-color: lightgreen; }}

The following example shows a menu that will float to the left of the page if
the viewport is 480 pixels wide or wider (if the viewport is less than
480 pixels, the menu will be on top of the content):

Example

@media screen and (min-width: 480px) { #leftsidebar
{width: 200px; float: left;} #main
{margin-left: 216px;}}

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

Abstract

HTML4 and CSS2 currently support media-dependent style sheets tailored
for different media types. For example, a document may use
sans-serif fonts when displayed on a screen and serif fonts when printed.
‘’ and ‘’ are two media types that have been defined.
Media queries extend the functionality of media types by allowing
more precise labeling of style sheets.

A media query consists of a media type and zero or more expressions that
check for the conditions of particular media features. Among the
media features that can be used in media queries are ‘’, ‘’, and ‘’. By using media queries, presentations can
be tailored to a specific range of output devices without changing the
content itself.

Так что же лучше использовать?

Обращайте внимание на стандартный вариант отображения конкретного элемента. Если вам нужно переписывать стандартное состояние для меньших экранов, то используйте max-width

Если элемент можно использовать на меньших экранах и при стандартном состоянии, применяйте min-width только в тех случаях, когда элемент должен отличаться от стандартного состояния. И конечно же, я рекомендую вам позволить контенту определять, что и как должно происходить.

Таблицы – отличный пример использования CSS div max width для изменения стандартного состояния элемента, чтобы он лучше отображался на маленьких экранах. Представьте таблицу, контента в которой слишком много, чтобы отображать его полностью на маленьких устройствах. В таком случае мы можем применить следующий код:

@media only screen and (max-width: 30em) {
  .big-table tr,
  .big-table td {
    display: block;
  }
}

Этот код позволит нам преобразовать каждую строку (и ячейку) в блок. В результате таблица может стать длинной по вертикали, но зачастую это меньшее из зол. Я имею в виду длинные таблицы, которые приходится прокручивать по горизонтали. В таких ситуациях лучше всего оставить таблицы без изменений, за исключением кода для тех браузеров, которые понимают медиа-запросы, и случаев, когда ширина экрана не превышает определенного значения (30em в нашем случае).

Другие элементы, которые в стандартном состоянии отлично смотрятся на маленьких экранах, нужно изменять лишь по необходимости для экранов большего размера. В таких случаях и применяется min-width.

Вкратце: позвольте стандартному состоянию элементов помочь вам определить, какой медиа-запрос использовать.

Media Queries For Menus

In this example, we use media queries to create a responsive navigation menu, that varies
in design on different screen sizes.

Large screens:

Home
Link 1
Link 2
Link 3

Small screens:

Home
Link 1
Link 2
Link 3

Example

/* The navbar container */.topnav { overflow: hidden;
background-color: #333;}/* Navbar links */.topnav a {  float:
left;  display: block;  color:
white;  text-align: center;  padding: 14px 16px;
text-decoration: none;}
/* On screens that are 600px wide or less, make the menu links stack on top
of each other instead of next to each other */@media screen and (max-width: 600px) {

.topnav a {    float: none;    width:
100%;  }}

Syntax

The media query syntax is described in terms of the CSS2 grammar. As such,
rules not defined here are defined in CSS2. The
production defined below replaces the
production from CSS2.

media_query_list
 : S* * ]?
 ;
media_query
 : ? S* media_type S* *
 | expression *
 ;
media_type
 : IDENT
 ;
expression
 : '(' S* media_feature S* ? ')' S*
 ;
media_feature
 : IDENT
 ;

COMMENT tokens, as defined by CSS2, do not occur in the grammar (to keep
it readable), but any number of these tokens may appear anywhere between
other tokens.

The following new definitions are introduced:

L  l|\\0{0,4}(4c|6c)(\r\n|)?|\\l
Y  y|\\0{0,4}(59|79)(\r\n|)?|\\y

The following new tokens are introduced:

{O}{N}{L}{Y}      {return ONLY;}
{N}{O}{T}         {return NOT;}
{A}{N}{D}         {return AND;}
{num}{D}{P}{I}    {return RESOLUTION;}
{num}{D}{P}{C}{M} {return RESOLUTION;}

is to be added to the CSS2
production.

CSS style sheets are generally case-insensitive, and this is also the
case for media queries.

In addition to conforming to the syntax, each media query needs to use
media types and media features according to their respective specification
in order to be considered conforming.

Only the first media query is conforming in the example below because
the «example» media type does not exist.

3.1. Error Handling

For media queries that are not conforming user agents need to follow the
rules described in this section.

Unknown media types. Unknown media types evaluate to
false. Effectively, they are treated identically to known media types
that do not match the media type of the device.

The media query «» will evaluate to false, unless
is actually a supported media type. Similarly,
«» will evaluate to true.

Unknown media types are distinct from media types that do
not actually match the IDENT production. Those fall under the malformed
media query clause.
Unknown media features. User agents are to represent
a media query as «» when one of the specified media
features is not known.

In this example, the first media query will be represented as
«» and evaluate to false and the second media query
is evaluated as if the first had not been specified, effectively.

Is represented as «» because the ‘’ feature does not accept the
‘’ prefix.
Unknown media feature values. As with unknown media
features, user agents are to represent a media query as «» when one of the specified media feature values is not known.

The media query specifies an unknown
value for the ‘’ media feature
and is therefore represented as «».

This media query is represented as «» because
negative lengths are not allowed for the ‘’ media feature:
Malformed media query. User agents are to handle
unexpected tokens encountered while parsing a media query by reading
until the end of the media query, while observing of (), [], {}, «», and », and correctly
handling escapes. Media queries with unexpected tokens are represented
as «».

The following is an malformed media query because having no space
between ‘’ and the expression is
not allowed. (That is reserved for the functional notation syntax.)

Media queries are expected to follow the error handling rules of the
host language as well.

… will not apply because the semicolon terminates the
rule in CSS.

Background

(This section is not normative.)

HTML4
and CSS2
currently support media-dependent style sheets tailored for different
media types. For example, a document may use different style sheets for
screen and print. In HTML4, this can be written as:

Inside a CSS style sheet, one can declare that sections apply to certain
media types:

The ‘’ and ‘’ media types are defined in HTML4. The
complete list of media types in HTML4 is: ‘’, ‘’, ‘’, ‘’, ‘’, ‘’, ‘’,
‘’. CSS2 defines the same list,
deprecates ‘’ and adds
‘’ and ‘’. Also, ‘’ is used to indicate that the style sheet
applies to all media types.

Media-specific style sheets are supported by several user agents. The
most commonly used feature is to distinguish between ‘’ and ‘’.

There have been requests for ways to describe in more detail what type
of output devices a style sheet applies to. Fortunately HTML4 foresaw
these requests and defined a forward-compatible syntax for media types.
Here is a quote from :

Media queries, as described in this specification, build on the
mechanism outlined in HTML4. The syntax of media queries fit into the
media type syntax reserved in HTML4. The
attribute of HTML4 also exists in XHTML and generic XML. The same syntax
can also be used inside in the ‘’
and ‘’ rules of CSS.

However, the parsing rules for media queries are incompatible with those
of HTML4 so that they are consistent with those of media queries used in
CSS.

HTML5 (at the moment of writing
still work in progress) references the Media Queries specification
directly and thus updates the rules for HTML.

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) {…}
