CSS property page template

Note: Remove this note block before publishing.


Page front matter:

The front matter at the top of the page is used to define "page metadata". The values should be updated appropriately for the particular property.

---
title: NameOfTheProperty
slug: Web/CSS/NameOfTheProperty
page-type: css-property OR css-shorthand-property
status:
  - experimental
  - deprecated
  - non-standard
browser-compat: css.properties.NameOfTheProperty
---
title

The title heading is displayed at the top of the page. The title format is NameOfTheProperty. For example, the background-color property has a title of background-color.

slug

The slug value is the end of the URL path after https://developer.mozilla.org/en-US/docs/. This will be formatted like Web/CSS/NameOfTheProperty. For example, the background-color property slug is Web/CSS/background-color.

page-type

The page-type key for CSS properties is css-shorthand-property for shorthand properties; otherwise it is css-property. For example, the page-type value for the animation property is css-shorthand-property but for the animation-delay property, it is css-property.

status

Include (appropriate) technology status keys: experimental, deprecated, non-standard (if not on a standards track).

browser-compat

Replace the placeholder value css.properties.NameOfTheProperty with the query string for the property in the Browser compat data repo.


Top-of-the-page macros

A number of macro calls appear at the top of the content section (immediately below the page front matter). You should update or delete them according to the advice below:

  • {{SeeCompatTable}} — this generates a This is an experimental technology banner that indicates the technology is experimental. If the technology you are documenting is not experimental, you can remove this. If it is experimental, and the technology is hidden behind a pref in Firefox, you should also fill in an entry for it in the Experimental features in Firefox page.
  • {{Deprecated_Header}} — this generates a Deprecated banner that indicates that use of the technology is discouraged. If it isn't, then you can remove the macro call.
  • {{CSSRef}} — this must be present on every CSS property page. It generates a suitable CSS sidebar, depending on what tags are included on the page. Remember to remove the {{MDNSidebar}} macro when you copy this page.

Other macros in the page

  • Formal definition and Formal syntax sections: The content of the Formal definition and Formal syntax sections is generated in place of the {{CSSInfo}} and {{CSSSyntax}} macros, respectively. For these sections to have data, you must ensure an appropriate entry has been filled in for the property in our properties.json data file. See properties.md for more information.
  • Specifications and Browser compatibility sections: The build tool automatically uses the browser-compat key-value pair to insert data into the Specifications and Browser compatibility sections (replacing the {{Specifications}} and {{Compat}} macros in those sections, respectively). Note that you may first need to create/update an entry for the property and its specification in our Browser compat data repo. See our compatibility tables guide for information on adding or editing entries.

Remember to remove this note block before publishing.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

In the introductory paragraph, start by naming the property and saying what it does. This should ideally be one or two short sentences.

Try it

This title is auto-generated by the macro {{EmbedInteractiveExample}}.

This section is for interactive examples added using the {{EmbedInteractiveExample}} macro. See the Interactive example demo section in our writing guidelines for more information.

Constituent properties

Add this section only for shorthand properties, such as animation, to list all the related longhand properties.

Syntax

Include the common use cases as a code block and describe the component subvalues that make up a complete value.

/* Insert code block showing common use cases */
/* or categories of values */

Values

Include one term and definition for each subvalue.

subvalue1

Include a description of the subvalue, its data type, and what it represents.

subvalue2

Include a description of the subvalue, its data type, and what it represents.

Description

This is an optional section to include a description of the property and explain how it works. Use this section to explain related terms and add use cases for the property.

Formal definition

{{CSSInfo}}

Remember to remove the backticks and backslash to use this macro.

Formal syntax

{CSSSyntax}}

Remember to remove the backticks and backslash to use this macro.

Examples

Note that we use the plural "Examples" even if the page only contains one example.

Add a descriptive heading

Each example must have an H3 heading (###) naming the example. The heading should be descriptive of what the example is doing. For example, "A simple example" does not say anything about the example and therefore, not a good heading. The heading should be concise. For a longer description, use the paragraph after the heading.

See our guide on how to add code examples for more information.

Note: Sometimes you will want to link to examples given on another page.

Scenario 1: If you have some examples on this page and some more examples on another page:

Include an H3 heading (###) for each example on this page and then a final H3 heading (###) with the text "More examples", under which you can link to the examples on other pages. For example:

## Examples

### Using the fetch API

Example of Fetch

### More examples

Links to more examples on other pages

Scenario 2: If you only have examples on another page and none on this page:

Don't add any H3 headings; just add the links directly under the H2 heading "Examples". For example:

## Examples

For examples of this API, see [the page on fetch()](https://example.org).

Accessibility concerns

This is an optional section. You can include any warnings here for accessibility concerns that developers should be aware of while using this property. You can also include workarounds for these accessibility concerns if there are any.

Specifications

{{Specifications}}

Remember to remove the backticks and backslash to use this macro.

Browser compatibility

{{Compat}}

Remember to remove the backticks and backslash to use this macro.
