The templates in this series are designed to be used in atable to make a cell with text in that cell, with an appropriately colored background. They are commonly used incomparison tables. Most of these templates should not be used simply to produce a background color, use them according to their meaning.
For example,{{yes}} makes a cell with a green background. The text in the cell is taken from the firstparameter;{{yes|Sure}} would give "Sure" otherwise it defaults to "Yes". Most templates allow editors to override the default text using|1= or equivalent, some require text to be placed after the template call, and others may need a vertical bar (|) separating the two:{{table cell template}} text or{{table cell template}} | text. This information, the colors, and default texts are found in the table below.
Important: If you want to use other attributes for the table cells that do not appear in§ Code below,e.g.colspan,rowspan, orstyle, they need to be put before the template call, and there must beno vertical bar (|) in-between them, for example:
Common code to most if not all the templates in this series:
| {{{1|text}}}
Code specific to this template:
style="background: #FFE3E3; color: black; vertical-align: middle; text-align: center; "|Nominated
Creating new templates
To make a new table cell template you can use:
{{subst:Table cell templates|text= default text|bg= background color|class= a class name without prefix|align= standard horizontal alignment}}
You should leave out thealign parameter and often theclass parameter is unnecessary, too.
Add the new template to the table in thecommon documentation afterwards. Please consider reusing one of the other templates and please choose the color sensibly.
If you find a table cell template that does not take a parameter and you want to be able to change the text in the cell,do not duplicate the template! Instead, edit the template and change the text to a default parameter substitution. For example, if a template's text isDropped, change that to{{{1|Dropped}}}.
When changing or creating a new template, follow theuse of colour guidelines and thecolor accessibility guidelines when choosing the background color and, sometimes, the text color. Many of these templates can be used with links to other articles or references, so the links should be clearly identifiable against the background color. You can check contrast level using theWebAIM contrast checker by setting the foreground color to theblue link color. Contrast should be at the minimum WCAG AA level and, whenever possible, at WCAG AAA level.Wikipedia:Manual of Style/Accessibility/Colors has a set of colors that comply with WCAG AAA and WCAG AA for unvisited links and normal text.
Color subpage
All templates should either have a/bgcolor subpage that contains nothing but a valid CSS color code, possibly wrapped innowiki tags, e.g.#BFD, which can be included withbackground: {{/bgcolor}}; in thestyle attribute, or they should reference another template's subpage, e.g.background: {{Template:Yes2/bgcolor}};. Alternatively, the/bgcolor subpage may redirect to another color code subpage:#REDIRECT [[yes2/bgcolor]].
This way, pages that are using these templates may also use{{legend}} and similar templates which can reference the actual color:{{legend|{{yes2/bgcolor}}|supported}}
