{{ombox |text=This template serves as the shared documentation for {{tl|Stack}}, {{tl|Stack begin}}, and {{tl|Stack end}}.}}

</noinclude>

This template can be used to stack images and other floating content such as infobox templates without causing problems with spacing and floating. Enter a string of images/templates as the first parameter to have them stack without generating floating errors or spacing errors. You can stack many objects from the top of a section and not force further subsections to space out.

{{TOClimit|3}}

=== Basic usage ===

== Usage ==

Using {{tld|stack}},

At its simplest:

<pre style="overflow: auto">

<syntaxhighlight lang="wikitext">

{{stack|<objects>}}

</syntaxhighlight>

</pre>

or, alternativelyAlternatively, using {{tld|stack begin}}/ and {{tld|stack end}}:

<syntaxhighlight lang="wikitext">

<pre style="overflow: auto">

{{stack begin}}

<objects>

{{stack end}}

</syntaxhighlight>

</pre>

Here,The <code><objectsobject></code> ismay simply be a string of wiki codewikicode for many images / templates.

==== Optional parameters ====

<syntaxhighlight lang="wikitext">

:<code><nowiki>{{</nowiki>stack| <objects> | float=left/'''right''' | clear=true/'''false'''<nowiki>}}</nowiki></code>

{{stack| <object(s)> | float=left or right | clear=true or false | margin=true or false}}

</syntaxhighlight>

or

<syntaxhighlight lang="wikitext">

:<code><nowiki>{{</nowiki>stack begin | float=left/'''right''' | clear=true/'''false'''<nowiki>}}</nowiki></code>

{{stack begin | float=left or right | clear=true or false | margin=true or false}}

</syntaxhighlight>

where

:*<code>float=</code> ''left'' or ''right'' (default is '''right''')

:*: This option can be used to float the stack to the left or right of the page

:*<code>clear=</code> ''true'' or ''false'' (default is '''false''')

:*: This option can be used to force the stack to the far left or right (e.g., near an infobox).

*margin= ''true'' or ''false'' (default is '''false''')

*: This option can be used to add a 1em margin to the left (for float right) or right (for float left).

You can also explicitly list multiple arguments:

===Basic examples===

<syntaxhighlight lang="wikitext">

To illustrate the utility of the stack templates, consider the following situation. We would like to have two right floating images at the top of the first section of our article (here, the "Lipsum" section), and one left floating image at the top of the second section (here, the Lorem section). To acheive this layout, without using a stack template, we could try the following code

{{stack| float=left or right | clear=true or false | margin=true or false

<pre>

|1=<object(s)>

=====Lipsum=====

|2=<object(s)>, etc. up to 9 parameters in the current version

[[File:Example.png|thumb|right|Example 1a]]

}}

[[File:Example.png|thumb|right|Example 1b]]

</syntaxhighlight>

* This multiple argument version does include extra vertical whitespace between each (set of) <code><object(s)></code>.

The result of this is shown in the [[#Without stack|without stack]] section below. Notice how the left floating image (Example 1c) is prevented from floating above the last right floating image (Example 1b). You may need to resize the width of your browser to fully appreciate the issue. To fix this problem, we can stack the two right floating images together, using the following code

===More examples===

{{tlf|Stack}} can also be used to float 1one or more images across a page.

It might take some experience to learn how the box area floats, in combination with various images or [[WP:Wikitables|wikitables]] on a page. The{{tlf|Stack}}'s operation of Template:stack is very quick, usingas theit uses an [[HTML]] &lt;table> featureto ofachieve theits [[HTML]] [[markup language]]effects.

===FloatFloating portal boxes===

{{tlf|Stack}} can be used to float a portal box beside an infobox (or other right-aligned item) when other methods might not work as anticipated.

Because auto-floating of portal boxes could cause a loss of margin control, the [[Template:stack]] can be used, as needed in some articles, when floating a portal box would look better alongside an infobox (or right-side image).

{| class={infobox

| '''label1=Infobox'''

<br>Line|data1=line 1 <br />Lineline 2 <br />Lineline 3 <br />Lineline 4 <br />L5line 5 <br />L6line 6 <br />L7line 7 <br />L8line 8 <br />L9line 9

|}}

[[File:Mona Lisa, by Leonardo da Vinci, from C2RMF retouched.jpg|thumb|right|60px|Test image]]

{| class="wikitable"

|style="width:33.0em<!--(was 420px)-->;"|

| width=420px|

AThis is a '''wikitable''' here,serving as a typical left-sidealigned table. The overlap on left-sidealigned tables had been a frequent problem with allowingwhen other boxes nearby were set to "float:right" on a page. So this is a test of how well a floating portal-box would avoid overlapping onto a left-side table.

{{stack |{{portal|Animals}}{{portal|Cats}} }}

The example here uses {{tld|stack}} to float 2 portal boxes (for Animals & Cats), as follows:

The example here uses {{tld|stack}} to float two portal boxes (Animals, Cats) as follows:

:* <nowiki>{{stack |{{portal|Animals}}{{portal|Cats}} }}

{{clear}}<syntaxhighlight lang="wikitext">

</nowiki>

{{stack |{{portal|Animals}}{{portal|Cats}} }}

The 2 portal-boxes are stacked together, and floated together as a stack, by both being listed in parameter 1 to {{tld|stack}}. Although the 2 portal-boxes were specified ''below'' the [[Mona Lisa]] image, because the infobox+image were also stacked together, then the {{tld|stack}} moved the 2 portal-boxes, even higher, alongside the infobox.

</syntaxhighlight>

The two portal-boxes are stacked and floated together by both being listed as {{tld|stack}}'s (first) parameter. Because the infobox and image were also stacked together, {{tld|stack}} moved the two portal-boxes alongside the infobox despite being after the image.

Normally, a portal-box would be stuck below the Mona Lisa image, causing this entire text section to format further below, and causing a large text-gap of empty whitespace to appear near the infobox. There is no limit to the number of portalboxes (or Commonscat boxes) which can be listed within a {{tld|stack}} call, such as in a stub or an article with many stacked images near the bottom. Using {{tld|stack}} is extremely efficient, due to being a short template which uses builtin tag &lt;table> to float the boxes.
