del

Definition

The del element is used to mark up modifications made to a document. Specifically, the del element is used to indicate that a section of content has changed and has therefore been removed.

By default, most Web browsers render content inside the del element with strike-through formatting.

The del element can be used as either a block element, or as an inline element. When used as a block element, the del element can contain block elements, inline elements, or text. When used as an inline element, the del element can only contain inline elements, or text.

Example

This example, where an entire paragraph has been removed, shows the del element used as a block element.

  1. <p>In 1994, five years after inventing the World Wide Web, Tim Berners-Lee ...</p>
  2. <del>
  3. <p>The rapid expansion of the Web into every area of society led ...</p>
  4. </del>
  5. <p><abbr>W3C</abbr> laid the foundations of today's Web with standards ...</p>

In the following example, text inside a paragraph has changed, and the del element is used as an inline element.

  1. <p>The price of lemonade is <del>35</del><ins>25</ins>¢ per glass.</p>

Best practice

Comments can be added to the title attribute to explain the reason content was removed. Web browsers may present these comments as tooltips when the cursor hovers above content marked up with del element.

Attributes

Advanced

cite
(URI) This attribute is intended to point to information explaining why content was changed. For example, this can be a URL leading to a Web page that contains such an explanation.
datetime
(Datetime) This is used to indicate the date and time when the content change was made.

Common core attributes

class
(NameTokens) This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or set of class names. Multiple class names must be separated by white space characters. Class names are typically used to apply CSS formatting rules to an element.
id
(ID) This attribute assigns an ID to an element. This ID must be unique in a document. This ID can be used by client-side scripts (such as JavaScript) to select elements, apply CSS formatting rules, or to build relationships between elements.
title
(Text) This attribute offers advisory information. Some Web browsers will display this information as tooltips. Assistive technologies may make this information available to users as additional information about the element.

Common internationalization attributes

xml:lang
(NameToken) This attribute specifies the base language of an element's attribute values and text content.
dir

  • ltr: Left-to-right
  • rtl: Right-to-left
