HTML <del> Tag
<del> tag represents deleted text in an HTML document.
Marking text as deleted is often used for determining differences between multiple versions of the same document. Browsers will typically strike a line through deleted text.
<del> tag is written as
</del> with the deleted text inserted between the start and end tags.
Basic Usage Example - A "To Do" List
<del> tag can be used in a "to do" list to markup items that have been done.
Date & Time
datetime attribute allows you to add a date and (optionally) a time. This attribute is mainly intended for private use (e.g. by server-side scripts collecting statistics about a site's edits), but it could potentially be displayed to users.
Here, we can add date and time information to items that have been crossed off our "to do" list.
You can add a citation using the
cite attribute. The value of this attribute must be the URL of a document that explains the change. This attribute is not intended for readers of the document. Rather, it is intended for private use (e.g. by server-side scripts collecting statistics about a site's edits).
Inserting New Text
Deleted text is often accompanied by inserted text. This often happens when out-dated information needs to be deleted and new information is added. To insert new text, use the
Deleting Table Rows &/or Columns
Delete Table Row
Delete Table Row
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.
<del> element accepts the following attributes.
This table shows the attributes that are specific to the
|cite||Indicates a source that should indicate the reason for the change.|
|datetime||Date and time of change.|
The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the
<del> tag , as well as with all other HTML tags.
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
<del> element, as well as any other HTML5 element.
For a full explanation of these attributes, see HTML 5 event handler content attributes.
Differences Between HTML 4 & HTML 5
Here's a template for the
<del> 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.
Here are the official specifications for the
- 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.
