Template documentation[view] [edit] [history] [purge]

Shortcut: {{bc}}

This template uses TemplateStyles:

Template:Block center/styles.css (sandbox)

This template uses block elements, e.g. <div> or <p>.
It should not be nested inside an inline element, e.g. <span>, or a template that produces such an element.

This template applies the class(es)
.wst-block-center
that can be targeted with a work's index styles.css using page styles

See H:DIVSPAN for details.

This template is used on approximately 167,000 pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

Usage

This template places a block of text in the center of the page, without affecting the text alignment within that block. {{Center block}} is another template which does the same thing.

{{bc}} is a shorter form of this template that redirects here.

Comparison of {{Block center}} and {{Center}}

This template retains the current text alignment (usually left), but moves the entire block of text into the center. To change to centered text alignment, use {{center}} instead.

Block center

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aenean commodo ligula eget dolor.

Aenean massa.

Center

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aenean commodo ligula eget dolor.

Aenean massa.

Parameters

All parameters are optional except for the text.

1, text, body: the text to be placed centrally as a block.
title: title of the block.
width: the width of the block (needs units which are valid CSS units).
max-width: the maximum width of the block (needs units which are valid CSS units).
height: the height of the block (needs units which are valid CSS units). Use adds pages to Category:Pages using center block with height parameter.
align: the text alignment within the block. One of left, right, center, justify; default is unspecified and so inherits from the parent.
class: additional CSS classes, which can be used in conjunction with index CSS. The classes wst-block-center and wst-block-center-title are always applied to the block and the title respectively.
style: additional CSS styles (prefer a class if the style is re-used within a work).

title

Where there is a need to give the title of the work, an optional "title" parameter can be used. Sometimes this is will center the title better than a stand-alone line will; other times not - it usually depends on if a fixed width (next example) is forced or not.

Example

{{block center|title=Lorem Ipsum|Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<br/>
Aenean commodo ligula eget dolor.

Aenean massa.}}

Lorem Ipsum

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aenean commodo ligula eget dolor.

Aenean massa.

width

Where there is a requirement to fix the width of the block, an optional "width" parameter can be used. Sometimes this is required to force a wider width when line wrap occurs.

Example

{{block center|width=25em|Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<br/>
Aenean commodo ligula eget dolor.

Aenean massa.}}

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aenean commodo ligula eget dolor.

Aenean massa.

For exactly the same "spacing" as rendered by normal paragraph(s) before and/or after the template-inserted content:

Note: this will force the width even when the page is narrower than the given width, up to the maximum specified by max-width, or 100% if that's not given.

Note: generally, avoid using percentages, as this will probably be unreasonably narrow on small screens. If the content is text, prefer text-relative CSS units, such as em. See H:PXWIDTH for more details.

max-width

This parameter provides a maximum width for the block, such that no matter how wide the parent container, the centered block will be no wider than this. Very often, this is a better choice than width, because it allows content to shrink on smaller screens like e-readers.

Example

{{block center|max-width=15em|Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna}}

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna

However, if the parent container is smaller that this value, the block will shrink as normal:

Example

<div style="width:10em; margin:auto;">
{{block center|max-width=15em|
Lorem ipsum dolor sit amet, consectetur adipisicing elit
}}
</div>

Lorem ipsum dolor sit amet, consectetur adipisicing elit

The two parameters can be combined. In this case, the width will be set according to the width parameter on small screens (below the max-width value), and then will be limited to the max-width value on large screens. Note that the width value has to change according to the parent size, so it's normally a percentage value (often 100%).

This is useful when there are floated blocks that don't cause the block to expand to the correct width, but where it's still desirable for the block to shrink on smaller screens:

Example

<div style="width:100%; border:1px dashed green;">
{{block center|max-width=40em|width=100%
|Wide parent: max-width of 40em applies.{{-}}{{float right|''Text on the right.''}}
}}
</div>

Wide parent: max-width of 40em applies.

Text on the right.

Example

<div style="width:30em; margin:auto; border:1px dashed green;">
{{block center|max-width=40em|width=100%
|Narrow parent: 100% width{{-}}{{float right|''Text on the right.''}}
}}
</div>

Narrow parent: 100% width

Text on the right.

height

Example

{{block center|height=15em|Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<br>
Aenean commodo ligula eget dolor.

Aenean massa.}}

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
Aenean commodo ligula eget dolor.

Aenean massa.

align

The text alignment within the (overall) centered block may be controlled using this parameter.

Example

{{block center|align=right|<poem>
Lorem ipsum dolor sit amet,
{{gap}}consectetuer adipiscing elit.
Aenean commodo ligula eget dolor;
{{gap}}Aenean massa.
</poem>}}

Lorem ipsum dolor sit amet,
consectetuer adipiscing elit.
Aenean commodo ligula eget dolor;
Aenean massa.

style

Where there is a need to specify the style of the text, an optional "style" parameter can be used. This parameter takes the same style attributes that can be set for any table.

Example

{{block center|style=font-style:italic|<poem>
Lorem ipsum dolor sit amet,
{{gap}}consectetuer adipiscing elit.
Aenean commodo ligula eget dolor;
{{gap}}Aenean massa.
</poem>}}

Lorem ipsum dolor sit amet,
consectetuer adipiscing elit.
Aenean commodo ligula eget dolor;
Aenean massa.

Spanning multiple pages

If you use many separate block centers you will find that every page has a slightly different alignment; however, this template cannot be left "dangling" and closed on another page to create one big block center. If you have a multipage block center, you can use {{Block center/s}} and {{Block center/e}} to open and close it on each page. Every page must have one of each, one at the start and one at the end. However, you may place one or both of them in the header or footer, so they will not be transcluded to the main namespace. When the pages are all transcluded, you will end up with just one {{Block center/s}} and just one {{Block center/e}} at the start and end of the section, respectively. See Help:Page breaks for more information.
