This template produces a box with links to a portal or to multiple portals. It is most often used in the "See also" section of an article.

Usage[سنواريو]

Basic usage
{{Portal |Portal 1 |Portal 2 |Portal 3 |... }}
All options
{{Portal
 | Portal 1
 | Portal 2
 | Portal 3
 | ... 
 | left = 
 | margin = 
 | break = 
 | boxsize = 
}}

Location[سنواريو]

Within articles, this template is meant to be placed at the bottom of the article in the See also section. If there is no See also section, you can put it in the External links section instead; there is no need to create a new section just to house this template. If there is no External links section either, just put it below the article text in the place that seems most appropriate.

There are no particular rules about the placement of portals on other kinds of page.

Image[سنواريو]

The portal image names are stored in subpages of Module:Portal/images, organised by the first letter of the portal name. For example, the first letter of Portal:Fishing is "F", so the image name is stored at Module:Portal/images/f. If there is an entry for a portal on the correct page then the corresponding image will be shown next to the portal link. If no image is found then File:Portal-puzzle.svg will be shown instead.

It is also possible to specify aliases for portal images. For example, the code {{portal|Detroit}} produces the same image as the code {{portal|Metro Detroit}}. The "Detroit" alias is found on the page Module:Portal/images/aliases.

The image-detection algorithm is case-insensitive. For example, the code {{portal|Detroit}} will produce the same image as the code {{portal|detroit}} (although the portal links will be different). Portal names are stored in lower case in the image subpages, and input is converted to lower case before being checked.

To add new images to the list, please make a protected edit request at Template talk:Portal to get an administrator to edit the correct subpage for you. Portal images must be either in the public domain or available under a free license that allows commercial reuse and derivative works; fair-use images are not acceptable.

Example[سنواريو]

Code Result
 {{Portal|سائنس}}

Parameters[سنواريو]

Name Value Description
1, 2, 3 ... The portal name, e.g. Literature The positional parameters specify the portals to be displayed.
left yes If set to yes, the portal appears on the left side of the page instead of the right.
margin CSS margin value, e.g. 1.2em 3em 0.5em 1em This allows you to set a custom margin. All valid CSS margin values are accepted.
break yes If set to yes, a line break is inserted after the portal name and before the word portal.
boxsize Size in pixels, e.g. 300 This sets a custom box width in pixels.

--[==[ This module is a Lua implementation of the old {{Portal}} template. As of August 2013 it is used on nearly 5,000,000 articles.
-- Please take care when updating it! It outputs two functions: p.portal, which generates a table of portals, and p.image, which
-- produces the image name for an individual portal.

-- The portal image data is kept in submodules of [[Module:Portal/images]], listed below:
-- [[Module:Portal/images/a]]       - for portal names beginning with "A".
-- [[Module:Portal/images/b]]       - for portal names beginning with "B".
-- [[Module:Portal/images/c]]       - for portal names beginning with "C".
-- [[Module:Portal/images/d]]       - for portal names beginning with "D".
-- [[Module:Portal/images/e]]       - for portal names beginning with "E".
-- [[Module:Portal/images/f]]       - for portal names beginning with "F".
-- [[Module:Portal/images/g]]       - for portal names beginning with "G".
-- [[Module:Portal/images/h]]       - for portal names beginning with "H".
-- [[Module:Portal/images/i]]       - for portal names beginning with "I".
-- [[Module:Portal/images/j]]       - for portal names beginning with "J".
-- [[Module:Portal/images/k]]       - for portal names beginning with "K".
-- [[Module:Portal/images/l]]       - for portal names beginning with "L".
-- [[Module:Portal/images/m]]       - for portal names beginning with "M".
-- [[Module:Portal/images/n]]       - for portal names beginning with "N".
-- [[Module:Portal/images/o]]       - for portal names beginning with "O".
-- [[Module:Portal/images/p]]       - for portal names beginning with "P".
-- [[Module:Portal/images/q]]       - for portal names beginning with "Q".
-- [[Module:Portal/images/r]]       - for portal names beginning with "R".
-- [[Module:Portal/images/s]]       - for portal names beginning with "S".
-- [[Module:Portal/images/t]]       - for portal names beginning with "T".
-- [[Module:Portal/images/u]]       - for portal names beginning with "U".
-- [[Module:Portal/images/v]]       - for portal names beginning with "V".
-- [[Module:Portal/images/w]]       - for portal names beginning with "W".
-- [[Module:Portal/images/x]]       - for portal names beginning with "X".
-- [[Module:Portal/images/y]]       - for portal names beginning with "Y".
-- [[Module:Portal/images/z]]       - for portal names beginning with "Z".
-- [[Module:Portal/images/other]]   - for portal names beginning with any other letters. This includes numbers,
--                                    letters with diacritics, and letters in non-Latin alphabets.
-- [[Module:Portal/images/aliases]] - for adding aliases for existing portal names. Use this page for variations
--                                    in spelling and diacritics, etc., no matter what letter the portal begins with.
--
-- The images data pages are separated by the first letter to reduce server load when images are added, changed, or removed.
-- Previously all the images were on one data page at [[Module:Portal/images]], but this had the disadvantage that all
-- 5,000,000 pages using this module needed to be refreshed every time an image was added or removed.
