HTML <hr> Tag
The HTML <hr>
tag represents a paragraph-level thematic break in an HTML document.
The <hr>
tag could be used in a scene change in a story, or a transition to another topic within a section of a reference book.
Syntax
The <hr>
tag is written as <hr>
(no end tag) with the new topic following the <hr>
element (and the old topic preceding it).
Like this:
Examples
Change of Topic
This example demonstrates how you can use the <hr>
tag to represent a change of topic within a section.
Note that the HTML5 specification states There is no need for an
<hr>
element between the sections themselves, since the <section>
elements and the <h1>
elements imply thematic changes themselves.
Change of Scene
Here, the <hr>
tag is used to represent a change of scene in a story.
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 <hr>
element accepts the following attributes.
Element-Specific Attributes
This table shows the attributes that are specific to the <hr>
tag/element.
Attribute | Description |
---|---|
None |
Global Attributes
The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the <hr>
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 <hr>
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

- onerror
- onfocus
- onformchange
- onforminput
- oninput
- oninvalid

Differences Between HTML 4 & HTML 5
The align
, noshade
, size
, and width
attributes are not supported in HTML5 (they were deprecated in HTML 4). Use CSS instead of these attributes.
Also, HTML 4 and previous versions defined the <hr>
element in terms of presentation only (i.e. that it represented a horizontal rule). HTML5 has changed this, so that it now represents a paragraph-level thematic break
. Note that most browsers usually present the <hr>
element as a horizontal rule, but it now has a specific semantic purpose, rather than purely presentation.
To see more detail on the two versions see HTML5 <hr>
Tag and HTML4 <hr>
Tag. Also check out the links to the official specifications below.
Template
Here's a template for the <hr>
tag with all available attributes for the tag (based on HTML5). These are grouped into attribute types, each type separated by a space. In many cases, you will probably only need one or two (if any) attributes. Simply remove the attributes you don't need.
For more information on attributes for this tag, see HTML5 <hr>
Tag and HTML4 <hr>
Tag.

Specifications
Here are the official specifications for the <hr>
element.
- HTML5 Specification (W3C)
- HTML Living Standard (WHATWG)
- Current W3C Draft (the next version that is currently being worked on)
- HTML 4 (W3C)
What's the Difference?
W3C creates "snapshot" specifications that don't change once defined. So the HTML5 specification won't change once it becomes an official recommendation. WHATWG on the other hand, develops a "living standard" that is updated on a regular basis. In general, you will probably find that the HTML living standard will be more closely aligned to the current W3C draft than to the HTML5 specification.
