How do I make a container box in HTML? — example

container-name

The container-name CSS property specifies a list of query container names used by the @container at-rule in a container query. A container query will apply styles to elements based on the size of the nearest ancestor with a containment context. When a containment context is given a name, it can be specifically targeted using the @container at-rule instead of the nearest ancestor with containment.

Syntax

/* A single name */ container-name: myLayout; /* Multiple names */ container-name: myPageLayout myComponentLibrary; /* Global Values */ container-name: inherit; container-name: initial; container-name: revert; container-name: revert-layer; container-name: unset; 

Values

A case-sensitive string that is used to identify the container.

The following conditions apply:

Examples

Using a container name

Given the following HTML example which is a card component with a title and some text:

div class="card"> div class="post-meta"> h2>Card titleh2> p>My post details.p> div> div class="post-excerpt"> p> A preview of my a href="https://example.com">blog posta> about cats. p> div> div> 

To create a containment context, add the container-type property to an element in CSS. The following example creates two containment contexts, one for the card meta information and one for the post excerpt:

Note: A shorthand syntax for these declarations are described in the container page.

.post-meta  container-type: inline-size; > .post-excerpt  container-type: inline-size; container-name: excerpt; > 

Writing a container query via the @container at-rule will apply styles to the elements of the container when the query evaluates to true. The following example has two container queries, one that will apply only to the contents of the .post-excerpt element and one that will apply to both the .post-meta and .post-excerpt contents:

@container excerpt (min-width: 400px)  p  visibility: hidden; > > @container (min-width: 400px)  p  font-size: 2rem; > > 

For more information on writing container queries, see the CSS Container Queries page.

Using multiple container names

You can also provide multiple names to a container context separated by a space:

.post-meta  container-type: inline-size; container-name: meta card; > 

This will allow you to target the container using either name in the @container at-rule. This is useful if you want to target the same container with multiple container queries where either condition could be true:

@container meta (max-width: 500px)  p  visibility: hidden; > > @container card (max-height: 200px)  h2  font-size: 1.5em; > >

container-name¶

Свойство container-name указывает список имен контейнеров запроса, используемых правилом @container в запросе контейнера.

Запрос контейнера будет применять стили к элементам на основе размера ближайшего предка с контекстом включения. Когда вмещающему контексту дается имя, он может быть специально нацелен с помощью правила @container вместо ближайшего предка с вмещающим элементом.

Спецификация¶

Примеры¶

Пример 1¶

Учитывая следующий пример HTML, который представляет собой компонент карты с заголовком и некоторым текстом:

 1 2 3 4 5 6 7 8 9 10 11 12 13

div class="card"> div class="post-meta"> h2>Card titleh2> p>My post details.p> div> div class="post-excerpt"> p> A preview of my a href="https://example.com">blog posta> about cats. p> div> div> 

Чтобы создать контекст включения, добавьте свойство container-type к элементу в CSS. В следующем примере создаются два контекста включения: один для метаинформации карты и один для выдержки из поста:

.post-meta  container-type: inline-size; > .post-excerpt  container-type: inline-size; container-name: excerpt; > 

При написании запроса контейнера с помощью at-правила @container стили будут применяться к элементам контейнера, когда запрос будет оценен как true . В следующем примере есть два контейнерных запроса, один из которых будет применяться только к содержимому элемента .post-excerpt , а другой — к содержимому как .post-meta , так и .post-excerpt :

@container excerpt (min-width: 400px)  p  visibility: hidden; > > @container (min-width: 400px)  p  font-size: 2rem; > > 

Пример 2¶

Вы также можете указать несколько имен для контекста контейнера, разделенных пробелом:

.post-meta  container-type: inline-size; container-name: meta card; > 

Это позволит вам нацеливаться на контейнер, используя любое имя в правиле @container . Это полезно, если вы хотите настроить таргетинг на один и тот же контейнер с несколькими запросами контейнера, где любое условие может быть истинным:

@container meta (max-width: 500px)  p  visibility: hidden; > > @container nav (max-height: 200px)  h2  font-size: 1.5em; > >

container

The container shorthand CSS property establishes the element as a query container and specifies the name or name for the containment context used in a container query.

Syntax

/* */ container: my-layout; /* / */ container: my-layout / size; /* Global Values */ container: inherit; container: initial; container: revert; container: revert-layer; container: unset; 

Values

A case-sensitive name for the containment context. More details on the syntax are covered in the container-name property page.

The type of containment context. More details on the syntax are covered in the container-type property page.

Formal definition

• container-name : none
• container-type : normal

• container-name : no
• container-type : no

• container-name : none or an ordered list of identifiers
• container-type : as specified

• container-name : Not animatable
• container-type : a color

Formal syntax

Example

Given the following HTML example which is a card component with an image, a title, and some text:

div class="post"> div class="card"> h2>Card titleh2> p>Card contentp> div> div> 

The explicit way to create a container context is to declare a container-type with an optional container-name :

.post  container-type: inline-size; container-name: sidebar; > 

The container shorthand is intended to make this simpler to define in a single declaration:

.post  container: sidebar / inline-size; > 

You can then target that container by name using the @container at-rule:

@container sidebar (min-width: 400px)  /* */ > 

For more information on container queries, see the CSS Container Queries page.
