Definition and Usage

The tag stands for the
«definition element», and it specifies a term that is going to be defined within
the content.

The nearest parent of the tag must also contain the definition/explanation for the term.

The term inside the tag can be any of the following:

1. Just as the content of the
element:

Example

<p><dfn>HTML</dfn> is the standard markup language for creating web pages.</p>

2. Or, with the title attribute added:

Example

<p><dfn title=»HyperText Markup Language»>HTML</dfn> is the standard markup language for creating web pages.</p>

3. Or, with an <abbr> tag inside the element:

Example

<p><dfn><abbr title=»HyperText Markup Language»>HTML</abbr></dfn> is the standard markup language for creating web pages.</p>

4. Or, with the id attribute added. Then, whenever a term
is used, it can refer back to the definition with an <a> tag:

Example

<p><dfn id=»html-def»>HTML</dfn> is the standard markup language for creating web pages.</p><p>This is some text…</p><p>This is some text…</p><p>Learn <a href=»#html-def»>HTML</a> now.</p>

Определение и использование

<dfn> Тег представляет собой определяющий экземпляр термина в HTML.

Экземпляр определение часто является первым использование термина в документе.

Ближайший родителем <dfn> тег также должен содержать определение / объяснение термина внутри <dfn> .

Термин внутри <dfn> тег может быть любое из следующих действий :

1. Содержание <dfn> элемент (без title атрибута):

пример

<p><dfn>HTML</dfn> is the standard markup language
for creating web
pages.</p>

2. title атрибут <dfn> тег:

пример

Можно также добавить атрибут идентификатора в <dfn> элемент. Затем, когда термин используется, он может вернуться к определению с использованием <a> тег:

пример

Attributes

Attributes can be added to an HTML element to provide more information about how the element should appear or behave.

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The element accepts the following attributes.

Element-Specific Attributes

This table shows the attributes that are specific to the tag/element.

Attribute	Description
None, but the attribute has special semantics for this element. If the tag has a attribute, then the exact value of that attribute is the term being defined.

Global Attributes

The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the tag , as well as with all other HTML tags.

accesskey
class
contenteditable
contextmenu
dir
draggable
dropzone
hidden
id
inert
itemid
itemprop
itemref
itemscope
itemtype
lang
spellcheck
style
tabindex
title
translate

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain «event» occurs. Each event handler content attribute deals with a different event.

Below are the standard HTML5 event handler content attributes.

Again, you can use any of these with the element, as well as any other HTML5 element.

onabort
oncancel
onblur
oncanplay
oncanplaythrough
onchange
onclick
oncontextmenu
ondblclick
ondrag
ondragend
ondragenter
ondragexit
ondragleave
ondragover
ondragstart
ondrop
ondurationchange
onemptied
onended
onerror
onfocus
onformchange
onforminput
oninput
oninvalid
onkeydown
onkeypress
onkeyup
onload
onloadeddata
onloadedmetadata
onloadstart
onmousedown
onmousemove
onmouseout
onmouseover
onmouseup
onmousewheel
onpause
onplay
onplaying
onprogress
onratechange
onreadystatechange
onscroll
onseeked
onseeking
onselect
onshow
onstalled
onsubmit
onsuspend

onvolumechange
onwaiting

For a full explanation of these attributes, see HTML 5 event handler content attributes.
