Module:Gridiron color/sandbox
This is the module sandbox page for Module:Gridiron color (diff). |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This Lua module is used on approximately 37,000 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them. |
The accessibility of this module is in question. The specific issue is: insufficient color contrast for some teams. Relevant discussion may be found on the talk page. |
This module depends on the following other modules: |
Implements:
- {{Gridiron primary color}}
- {{Gridiron primary style}}
- {{Gridiron alt primary style}}
- {{Gridiron secondary color}}
- {{Gridiron alt primary color}}
- {{Gridiron alt secondary color}}
Uses color data from Module:Gridiron color/data.
Usage
[edit]Debugging
[edit]Displays entire row from Module:Gridiron color/data for team and year passed in template call or using |team=
and |year=
(if omitted from invoke, module will take values from the template call):
{{#invoke:Gridiron color|test|team=team name (optional)|year=#### (optional)}}
["Buffalo Bills"] = {{ "#00274D", #FFFFFF", #C60C30", #C60C30", #FFFFFF"}}
Return team color
[edit]Returns either raw color value or prefixed color value. |column=
uses the following values:
- Primary color (background)
- Secondary color (text)
- Tertiary color raw (border)
- Alt primary color
- Alt secondary color
Set |raw=true
to display raw hex values. Team name and year passed in template call or specified using |team=
and |year=
:
{{#invoke:Gridiron color|color|column=#|raw=true (optional)|team=team name (optional)|year=#### (optional)}}
background: #00274D
Return team style
[edit]Returns complete CSS style for given team. A border will be displayed using the tertiary color if |border=
is set to "true" (in which case the border will be 2px wide) or to a positive integer value (in which case the width will be the value specified in pixels). Team name and year passed in template call or specified using |team=
and |year=
:
{{#invoke:Gridiron color|style|border=# or yes (optional)|team=team name (optional)|year=#### (optional)}}
background-color: #00274D !important; color: #FFFFFF !important; box-shadow: inset 2px 2px 0 #C60C30, inset -2px -2px 0 #C60C30;
