Тег (от англ. division — раздел) является универсальным блочным элементом и предназначен для группирования элементов документа с целью изменения вида содержимого через стили. Для этого добавляется атрибут class или id с именем класса или идентификатора.
Синтаксис¶
Закрывающий тег обязателен.
Атрибуты¶
Для этого элемента доступны универсальные атрибуты.

Элемент разделения контента HTML ( ) является универсальным контейнером для потокового контента. Он не влияет на контент или макет до тех пор, пока не будет стилизован с помощью CSS.
Интерактивный пример
Являясь «чистым» контейнером, элемент , по существу, не представляет ничего. Между тем, он используется для группировки контента, что позволяет легко его стилизовать, используя атрибуты class или id , помечать раздел документа, написанный на разных языках (используя атрибут lang ), и так далее.
Категории контента
Потоковый контент, явный контент.
Допустимое содержимое
Потоковый контент или (в WHATWG HTML), если родительским является элемент : один или несколько элементов , сопровождаемых одним или более элементами , в ряде случаев смешанных с элементами и .
Пропуск тегов
Ни одного; Оба тега, открывающий и закрывающий, являются обязательными.
Допустимые родители
Любой элемент, который разрешает потоковый контент в качестве содержимого.. Или (в WHATWG HTML): элемент .
Допустимые ARIA-роли
Любые
DOM-интерфейс
HTMLDivElement
Атрибуты
К этому элементу применимы глобальные атрибуты.
Примечание: Атрибут align устарел и вышел из употребления; не используйте его больше. Вместо этого, вам следует использовать свойства CSS или методы, такие как CSS Grid или CSS Flexbox для выравнивания и изменения положения элементов на странице.
Примечание
Элемент следует использовать только в том случае, если никакой другой семантический элемент (такой как или ) не подходит.
Примеры
Простой пример
div>p>Любой тип контента. Например, <p>, <table>. Все что угодно!p>div>
Результат будет выглядеть так:
Стилизованный пример
Этот пример создаёт прямоугольник с тенью, применяя стили к с помощью CSS. Заметьте, что использование атрибута class на элементе даёт применение стилей «shadowbox» (в дословном переводе означает «теневая коробка») к элементу.
HTML
divclass="shadowbox">p>Вот очень интересная заметка в прекрасном прямоугольнике с тенью.p>div>
The HTML class attribute is used to specify a class for an HTML element.
Multiple HTML elements can share the same class.
Using The class Attribute
The class attribute is often used to point to a class name in a style sheet. It can also be used by a JavaScript to access and manipulate elements with the specific class name.
In the following example we have three elements with a class attribute with the value of «city». All of the three elements will be styled equally according to the .city style definition in the head section:
Example
London
London is the capital of England.
Paris
Paris is the capital of France.
Tokyo
Tokyo is the capital of Japan.
In the following example we have two elements with a class attribute with the value of «note». Both elements will be styled equally according to the .note style definition in the head section:
Example
My Important Heading
This is some important text.
Tip: The class attribute can be used on any HTML element.
Note: The class name is case sensitive!
Tip: You can learn much more about CSS in our CSS Tutorial.
The Syntax For Class
To create a class; write a period (.) character, followed by a class name. Then, define the CSS properties within curly braces <>:
Example
Create a class named «city»:
London is the capital of England.
Paris is the capital of France.
Tokyo is the capital of Japan.
Multiple Classes
HTML elements can belong to more than one class.
To define multiple classes, separate the class names with a space, e.g. . The element will be styled according to all the classes specified.
In the following example, the first element belongs to both the city class and also to the main class, and will get the CSS styles from both of the classes:
Example
London
Different Elements Can Share Same Class
Different HTML elements can point to the same class name.
In the following example, both and
point to the «city» class and will share the same style:
Example
Use of The class Attribute in JavaScript
The class name can also be used by JavaScript to perform certain tasks for specific elements.
JavaScript can access elements with a specific class name with the getElementsByClassName() method:
Example
Click on a button to hide all elements with the class name «city»:
Don’t worry if you don’t understand the code in the example above.
You will learn more about JavaScript in our HTML JavaScript chapter, or you can study our JavaScript Tutorial.

The div tag is known as Division tag. The div tag is used in HTML to make divisions of content in the web page like (text, images, header, footer, navigation bar, etc). Div tag has both open (
) and closing (
) tag and it is mandatory to close the tag. The Div is the most usable tag in web development because it helps us to separate out data in the web page and we can create a particular section for particular data or function in the web pages.
Div tag is Block level tag
It is a generic container tag
It is used to group various tags of HTML so that sections can be created and styles can be applied to them.
As we know Div tag is block-level tag, the div tag contains entire width. Hence, every div tag will start from a new line, and not the same line.
html
As we know, div tag is used for grouping HTML elements together and to apply CSS and create web layouts using it. In the below example we don’t use div tag and hence we need to apply CSS for each tag (in the example using H1 H2 and two paragraphs p tags)
html
Creating Web Layout using Div Tag The div tag is a container tag. Inside div tag, we can put more than one HTML element and can group them together and apply CSS for them. Div tag can be used for creating a layout of web pages. In the below example we had created a web layout using the div tag. We can also create web layouts using table tag but table tags are very complex to modify the layout. The div tag is very flexible in creating web layouts and easy to modify. The below example will show grouping of HTML element using div tag and create block-wise web layout.
html
Using Div tag we can cover the gap between the heading tag and the paragraph tag. This example will display a web layout with three blocks.
We can use CSS in any of the divisions ( tag) using the following methods:
1. Using class: We can use class on that particular div and apply CSS either inside a tag or linking an external CSS file.

2. Inline CSS: We can directly use CSS in div also. This method does not require class. Div in HTML coding is used as a container tag also because it is the one that can contain all other tags.

Difference Between div tag and span tag
The div and span tags are two commonly used tags when creating pages using HTML and performs different functionality. While div tag is a block level element and span is an inline element The div tag creates a line break and by default creates a division between the text that comes after the tag as begun and until the tag ends with
. div tag creates separate boxes or containers for all elements inside this tag like text, images, paragraphs.

The span tag does not create a line break similar to a div tag, but rather allows the user to separate things from other elements around them on a page within the same line. avoiding of line break, results only that selected text to change, keeping all the other elements around them same. Below example will display the difference between span and div tag while div tag contains whole width and span tag contain only required width and rest parts are free for another element.
