W celu wyświetlenia dokumentacji w zorganizowany, znormalizowany i łatwy do odczytania sposób, przewodnik stylu Mozilla Developer Network opisuje, w jaki sposób tekst powinien być zorganizowany, zapisany, sformatowany i tak dalej. Są to wytyczne, a nie surowe zasady. Jesteśmy bardziej zainteresowani treścią niż formatowaniem, nie jesteś zobowiązany do uczenia się całego przewodnika po stylach MDN przed wniesieniem wkładu. Nie bądź jednak zdenerwowany lub zaskoczony, jeśli inny tłumacz zmodyfikuje w późniejszym czasie edytowany przez ciebie artykuł, aby dostosować się go, do głównych wytycznych stawianych dokumnetacji MDN.

Jeśli szukasz informacji jak dany typ strony powinien być ustrukturyzowany, zobacz poradnik dotyczący układu stron MDN

Aspekty językowe tego przewodnika dotyczą przede wszystkim dokumentacji w języku angielskim. Inne kraje mogą mieć (i mogą tworzyć) przewodniki po stylach we własnym języku. Tłumaczenia takie powinny być opublikowane jako podstrony, na lokalnych stronach MDN, dedykowanych dla danego języka przez zespół zajmujący się tłumaczeniami tzw. zespół lokalizacyjny.

Podstawy

Tytuły stron

Tytuły stron używane są w wynikach wyszukiwania, dzięki temu łatwiej jest znaleźć stronę w wynikach organicznych wyszukiwarek. Tytuły służą również do zachowania odpowiedniej struktury strony. Dlatego wraz z menu okruszkowym lub inaczej okruszkami(z ang. breadcrumbs)  umieszczane są na górze strony, w celu zachowania odpowiedniej jej hierarchii. Tytuł,  wyświetlany na górze w oknie przeglądarki, może różnić się od tzw. slug'a, który jest elemnetem adresu URL, następującym po "<locale>/docs/".

Tytuł i wielkie litery(kapitaliki)

Tytuły stron i nagłówki sekcji(H1-H6) powinny być formatowane w taki sam sposób jak zdania. Wielka litera powinna być pisana na początku pierwszego słowa, również powinna wystąpić w nazwach własnych. Powinieneś unikać słów pisanych tzw. pismem wielbłądzim(które w anglojęzycznych krajach jest stosowane w tytułach):

Choosing titles and slugs

Page slugs should be kept short; when creating a new level of hierarchy, the new level's component in the slug should generally just be a word or two.

Page titles, on the other hand, may be as long as you like, within reason, and they should be descriptive.

Creating new subtrees

When you need to add a number of articles about a topic or topic area, you will typically do so by creating a landing page, then adding subpages for each of the individual articles. The landing page should open with a paragraph or two describing the topic or technology, then provide a list of the subpages with descriptions of each page. You can automate the insertion of pages into the list using a number of macros we've created.

For example, consider the JavaScript guide, which is structured like this:

Try to avoid putting your article at the top of the hierarchy, which slows the site down and makes search and site navigation less effective.

Sections, paragraphs, and newlines

Use heading levels in decreasing order: {{HTMLElement("h2")}} then {{HTMLElement("h3")}} then {{HTMLElement("h4")}}, without skipping levels. H2 is the highest level allowed because H1 is reserved for the page title. If you need more than three or four levels of headers you should consider breaking up the article into several smaller articles with a landing page, linking them together using the {{TemplateLink("Next")}}, {{TemplateLink("Previous")}}, and {{TemplateLink("PreviousNext")}} macros.

The enter (or return) key on your keyboard starts a new paragraph. To insert a newline without a space, hold down the shift key while pressing enter.

Text formatting and styles

Use the "Formatting Styles" drop-down list to apply predefined styles to selected content.

Note: The "Note" style is used to call out important notes, like this one.
Warning: Similarly, the "Warning" style creates warning boxes like this.

Unless specifically instructed to do so, do not use the HTML style attribute to manually style content. If you can't do it using a predefined class, drop into Matrix and ask for help.

Code sample style and formatting

Tabs and line breaks

Use two spaces per tab in all code samples. Code should be indented cleanly, with open-brace ("{") characters on the same line as the statement that opens the block. For example:

if (condition) {
  /* handle the condition */
} else {
  /* handle the "else" case */
}

Long lines shouldn't be allowed to stretch off horizontally to the extent that they require horizontal scrolling to read. Instead, break at natural breaking points. Some examples follow:

if (class.CONDITION || class.OTHER_CONDITION || class.SOME_OTHER_CONDITION
       || class.YET_ANOTHER_CONDITION ) {
  /* something */
}

var toolkitProfileService = Components.classes["@mozilla.org/toolkit/profile-service;1"]
                           .createInstance(Components.interfaces.nsIToolkitProfileService);

Inline code formatting

Use the "Code" button (labeled with two angle brackets "<>") to apply inline code-style formatting to function names, variable names, and method names (this uses the {{HTMLElement("code")}} element). For example, "the frenchText() function".

Method names should be followed by a pair of parentheses: doSomethingUseful(). This helps to differentiate methods from other code terms.

Syntax highlighting

Screenshot of the "syntax highlighting" menu.Entire lines (or multiple lines) of code should be formatted using syntax highlighting rather than the {{HTMLElement("code")}} element. Click the "pre" button in the toolbar to create the preformatted content box in which you'll then write your code. Then, with the text entry cursor inside the code box, select the appropriate language from the language list button to the right of the "pre" button, as seen in the screenshot to the right. The following example shows text with JavaScript formatting:

for (var i = 0, j = 9; i <= 9; i++, j--)
  document.writeln("a[" + i + "][" + j + "]= " + a[i][j]);

If no appropriate transformation is available, use the pre tag without specifying a language ("No Highlight" in the language menu).

Styling HTML element references

There are various specific rules to follow when writing about HTML elements, in order to consistently describe the various components of elements, and to ensure that they're properly linked to detailed documentation.

Element names
Use the {{TemplateLink("HTMLElement")}} macro, which creates a link to the page for that element. For example, writing \{{HTMLElement("title")}} produces "{{HTMLElement("title")}}". If you don't want to create a link, enclose the name in angle brackets and use "Code (inline)" style (e.g., <title>).
Attribute names
Use bold face.
Attribute definitions
Use the {{TemplateLink("htmlattrdef")}} macro (e.g., \{{htmlattrdef("type")}}) for the definition term, so that it can be linked to from other pages, then use the {{TemplateLink("htmlattrxref")}} macro (e.g., \{{htmlattrxref("attr","element")}}) to reference attribute definitions.
Attribute values
Use "Code (inline)" style, and do not use quotation marks around strings, unless needed by the syntax of a code sample. E.g.: When the type attribute of an <input> element is set to email or tel ...
Labeling attributes
Use labels like {{HTMLVersionInline(5)}} thoughtfully. For example, use them next to the bold attribute name but not for every occurrence in your body text.

Latin abbreviations

In notes and parentheses

In running text

Meanings and English equivalents of Latin abbreviations

Abbrev Latin English
cf. confer compare
e.g. exempli gratia for example
et al. et alii and others
etc. et cetera and so forth, and so on
i.e. id est that is, in other words
N.B. nota bene note well
P.S. post scriptum postscript

Note: Always consider whether it's truly beneficial to use a Latin abbreviation. Some of these are used so rarely that many readers won't understand the meaning, and others are often confused with one another. And be sure that you use them correctly, if you choose to do so. For example, be careful not to confuse "e.g." with "i.e.", which is a common error.

Acronyms and abbreviations

Capitalization and periods

Use full capitals and delete periods in all acronyms and abbreviations, including organizations such as "US" and "UN".

Expansion

On the first mention of a term on a page, expand acronyms likely to be unfamiliar to users. When in doubt, expand it, or, better, link it to the article or glossary entry describing the technology.

Plurals of acronyms and abbreviations

For plurals of acronyms or abbreviations, add s. Don't use an apostrophe. Ever. Please.

Capitalization

Use standard English capitalization rules in body text, and capitalize "World Wide Web" and "Web".

Contractions

Use contractions (e.g. "don't", "can't", "shouldn't") if you prefer. We're not that formal!

Pluralization

Use English-style plurals, not the Latin- or Greek-influenced forms.

Hyphenation

Hyphenate compounds when the last letter of the prefix is a vowel and is the same as the first letter of the root.

Gender-neutral language

It is a good idea to use gender-neutral language in any kind of writing where gender is irrelevant to the subject matter, to make the text as inclusive as possible. So for example, if you are talking about the actions of a specific man, usage of he/his would be fine, but if the subject is a person of either gender, he/his isn't really appropriate.

Let's take the following example:

A confirmation dialog appears, asking the user if he allows the web page to make use of his web cam.

A confirmation dialog appears, asking the user if she allows the web page to make use of her web cam.

Both versions in this case are gender-specific. This could be fixed by using gender-neutral pronouns:

A confirmation dialog appears, asking the user if they allow the web page to make use of their web cam.

Note: MDN allows the use of this very common syntax (which is controversial among usage authorities), in order to make up for the lack of a neutral gender in English. The use of the third-person plural as a neutral gender pronoun (that is, using "they," them", "their," and "theirs") is an accepted practice, commonly known as "singular 'they.'"

You can use both genders:

A confirmation dialog appears, asking the user if he or she allows the web page to make use of his/her web cam.

making the users plural:

A confirmation dialog appears, asking the users if they allow the web page to make use of their web cams.

The best solution, of course, is to rewrite and eliminate the pronouns completely:

A confirmation dialog appears, requesting the user's permission for web cam access.

A confirmation dialog box appears, which asks the user for permission to use the web cam.

The last way of dealing with the problem is arguably better, as it is not only grammatically more correct but removes some of the complexity associated with dealing with genders across different languages that may have wildly varying gender rules. This can make translation easier, both for readers reading English, then translating it into their own language as they read, and for localizers translating articles into their own language.

Numbers and numerals

Dates

For dates (not including dates in code samples) use the format "January 1, 1990".

Alternately, you can use the YYYY/MM/DD format.

Decades

For decades, use the format "1990s". Don't use an apostrophe.

Plurals of numerals

For plurals of numerals add "s". Don't use an apostrophe.

Commas

In running text, use commas only in five-digit and larger numbers.

Punctuation

Serial comma

Use the serial comma. The serial (also known as "Oxford") comma is the comma that appears before the conjunction in a series of three or more items.

Note: This is in contrast to the One Mozilla style guide, which specifies that the serial comma is not to be used. MDN is an exception to this rule.

Spelling

For words with variant spellings, always use the first entry at Answers.com. Do not use variant spellings.

Terminology

Obsolete vs. deprecated

It's important to be clear on the difference between the terms obsolete and deprecated.

Obsolete:
On MDN, the term obsolete marks an API or technology that is not only no longer recommended, but also no longer implemented in the browser. For Mozilla-specific technologies, the API is no longer implemented in Mozilla code; for Web standard technology, the API or feature is no longer supported by current, commonly-used browsers.
Deprecated:
On MDN, the term deprecated marks an API or technology that is no longer recommended, but is still implemented and may still work. These technologies will in theory eventually become obsolete and be removed, so you should stop using them. For Mozilla-specific technologies, the API is still supported in Mozilla code; for Web standard technology, the API or feature has been removed or replaced in a recent version of the defining standard.

HTML elements

Use "elements" to refer to HTML and XML elements, rather than "tags". In addition, they should almost always be wrapped in "<>", and should be in the {{HTMLElement("code")}} style. Also, at least the first time you reference a given element in a section should use the {{TemplateLink("HTMLElement")}} macro, to create a link to the documentation for the element (unless you're writing within that element's reference document page).

User interface actions

In task sequences, describe user interface actions using the imperative mood. Identify the user interface element by its label and type.

Voice

While the active voice is generally preferred, the passive voice is also acceptable, given the informal feel of our content. Try to be consistent, though.

Wiki markup and usage

To automatically create a link to a Bugzilla bug, use this template:

\{{Bug(322603)}}

This results in:

{{Bug(322603)}}

For WebKit bugs, you can use this template:

\{{Webkitbug("322603")}}

This results in:

{{Webkitbug("322603")}}

Page tags

Tags provide meta information about a page and/or indicate that a page has specific improvements needed to its content. Every page in the wiki should have tags. You can find details on tagging in our How to properly tag pages guide.

The tagging interface lives at the bottom of a page while you're in edit mode, and looks something like this:

Screenshot of the UX for adding and removing tags on MDN

To add a tag, click in the edit box at the end of the tag list and type the tag name you wish to add. Tags will autocomplete as you type. Press enter (or return) to submit the new tag. Each article may have as many tags as needed. For example, an article about using JavaScript in AJAX programming might have both "JavaScript" and "AJAX" as tags.

To remove a tag, simply click the little "X" icon in the tag.

Tagging pages that need work

In addition to using tags to track information about the documentation's quality and content, we also use them to mark articles as needing specific types of work.

Tagging obsolete pages

Use the following tags for pages that are not current:

SEO summary

The SEO summary is a very short summary of the page. It will be reported as a summary of the article to robots crawling the site, and will then appear in search results for the page. It is also used by macros that automate the construction of landing pages inside MDN itself.

By default, the first pagragraph of the page is used as the SEO summary. However you can override this behavior by marking a section with the "SEO summary" style in the WYSIWYG editor.

Landing pages

Landing pages are pages at the root of a topic area of the site, such as the main CSS or HTML pages. They have a standard format that consists of three areas:

  1. A brief (typically one paragraph) overview of what the technology is and what it's used for. See {{anch("Writing a landing page overview")}} for tips.
  2. A two-column list of links with appropriate headings. See {{anch("Creating a page link list")}} for guidelines.
  3. An optional "Browser compatibility" section at the bottom of the page.

Creating a page link list

The link list section of an MDN landing page consists of two columns. These are created using the following HTML:

<div class="row topicpage-table">
  <div class="section">
    ... left column contents ...
  </div>
  <div class="section">
    ... right column contents ...
  </div>
</div>

The left-hand column should be a list of articles, with an <h2> header at the top of the left column explaining that it's a list of articles about the topic (for example "Documentation and tutorials about foo"); this header should use the CSS class "Documentation". Below that is a <dl> list of articles, with each article's link in a <dt> block and a brief one-or-two sentence summary of the article in the corresponding <dd> block.

The right-hand column should contain one or more of the following sections, in order:

Getting help from the community
This should provide information on Matrix chat rooms and mailing lists available about the topic. The heading should use the class "Community".
Tools
A list of tools the user can look at to help with the use of the technology described in this section of MDN. The heading should use the class "Tools".
Related topics
A list of links to landing pages for other, related, technologies of relevance. The heading should use the class "Related_Topics".

<<<finish this once we finalize the landing page standards>>>

Using, inserting images

It's sometimes helpful to provide an image in an article you create or modify, especially if the article is very technical. To include an image:

  1. Attach the desired image file to the article (at the bottom of every article in edit mode)
  2. Create an image in the WYSIWYG editor
  3. In the WYSIWYG editor in the drop-down list listing attachments, select the newly created attachment which is your image
  4. Press OK.
