Адаптивный и мобильный дизайн с css3 media queries

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.

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) {…}

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%;  }}

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.

Add a Breakpoint

Earlier in this tutorial we made a web page with rows and columns, and it
was responsive, but it did not look good on a small screen.

Media queries can help with that. We can add a breakpoint where
certain parts of the design will behave differently on each side of the
breakpoint.

Desktop

Phone

Use a media query to add a breakpoint at 768px:

Example

When the screen (browser window) gets smaller than 768px, each column should have a width of 100%:

/* 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%;}@media only screen and (max-width: 768px) {  /* For mobile phones: */
 
{    width: 100%;  }}

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.

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;  }}

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:

<link rel=»stylesheet» media=»mediatype and|not|only (expressions)»
href=»print.css»>

Using width, max-width and margin: auto;

As mentioned in the previous chapter; a block-level element always takes up the full width available
(stretches out to the left and right as far as it can).

Setting the of a block-level element will prevent it from stretching
out to the edges of its container. Then, you can set the
margins to auto, to horizontally center the element within its container. The
element will take up the specified width, and the remaining space will be split
equally between the two margins:

This <div> element has a width of 500px, and margin set to auto.

Note: The problem with the above occurs when the browser window is
smaller than the width of
the element. The browser then adds a horizontal scrollbar to the page.

Using instead, in this situation, will improve the
browser’s handling of small windows. This is important when making a site usable
on small devices:

This <div> element has a max-width of 500px, and margin set to auto.

Tip: Resize the browser window to less than 500px wide, to see the difference between
the two divs!

Here is an example of the two divs above:

Example

div.ex1 {  width: 500px;  margin:
auto;  border: 3px solid #73AD21;}div.ex2 {  max-width: 500px; 
margin: auto;  border: 3px solid #73AD21;}

Ориентир на настольные ПК и max-width

Большая часть разработчиков до сих пор ориентируется только на пользователей ПК. Часто осознание ситуации приходит, когда становится ясно, сколько сил было потрачено впустую на компоненты для ПК, которые все реже востребованы из-за растущего числа мобильных пользователей. При анализе стилей подобных сайтов чаще всего встречается CSS media max width.

Если дизайн разрабатывался в первую очередь под настольные ПК, значит весь CSS должен быть насыщен объемным кодом для других ключевых точек (breakpoints). Если определенная ширина, заданная для ПК, является точкой отсчета, и мы не станем изменять и переписывать наш CSS, то вполне логично будет поменять в базовых стилях значения ширины окна просмотра на те, которые мы собираемся применять к экранам меньшего размера.

Вот пример, которым я часто пользуюсь (предполагая, что .related принимает форму боковой панели):

.content {
  width: 60%;
}

.related {
  width: 40%;
}

@media screen and (max-width: 37.4em) {
  .content,
  .related {
    width: 100%;
  }
}

Такой подход при использовании со множеством компонентов может существенно увеличить объем CSS завершенного проекта. Но так как блочные элементы по умолчанию занимают 100% ширины родительского элемента, то разумнее было бы прописать все следующим образом:

@media screen and (min-width: 37.5em) {
  .content {
    width: 60%;
  }

  .related {
    width: 40%;
  }
}

Здесь мы используем стандартное положение блочных элементов, и перекрываем их, когда это состояние требуется изменить. Чтобы лучше понять суть всего сказанного, нужно изучить рабочий код таких сайтов.

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.

Always Design for Mobile First

Mobile First means designing for mobile before designing for desktop or any
other device (This will make the page display faster on smaller devices).

This means that we must make some changes in our CSS.

Instead of changing styles when the width gets smaller than
768px, we should change the design when the width gets larger than
768px. This will make our design Mobile First:

Example

/* For mobile phones: */ {  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%;}}

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;  }}
