TWiki Skins 
Skins overlay regular templates with alternate header/footer layouts; topic text is not affected
 Overview 
Skins are customized 
TWikiTemplates files. You can use skins to change the look of a TWiki topic, for example, the layout of the header and footer. Rendered text between header and footer does 
not change. You can also use skins to define an alternate view, like a view optimized for printing.
 Defining Skins 
Skin files are located in the 
twiki/templates directory and are named with the syntax: 
<scriptname>.<skin>.tmpl. For example, the 
Printable skin for the 
view template is 
view.print.tmpl.
Use the existing 
TWikiTemplates (like 
view.tmpl) or skin files as a base for your own skin, name it for example 
view.myskin.tmpl.
 Variables in Skins 
You can use 
template variables, 
TWikiVariables, and other predefined variables to compose your skins. Some commonly used variables in skins:
| Variable: | Expanded to: | 
| %WIKILOGOURL% | Link of page logo | 
| %WIKILOGOIMG% | Image URL of page logo | 
| %WIKILOGOALT% | Alt text of page logo | 
| %WEBBGCOLOR% | Web specific background color, defined in the WebPreferences | 
| %WIKITOOLNAME% | The name of your TWiki site | 
| %SCRIPTURL% | The script URL of TWiki | 
| %SCRIPTSUFFIX% | The script suffix, ex: .pl,.cgi | 
| %WEB% | The name of the current web. Note: It is recommended to URL-encode the variable in form actions with %INTURLENCODE{"%WEB%"}%for proper handling in an internationalized environment | 
| %TOPIC% | The name of the current topic. Note: It is recommended to URL-encode the variable in form actions with %INTURLENCODE{"%TOPIC%"}%for proper handling in an internationalized environment | 
| %WEBTOPICLIST% | Common links of current web, defined in the WebPreferences. It includes a #GoBox | 
| %TEXT% | The topic text, e.g. the content that can be edited | 
| %META{"form"}% | TWikiForm, if any | 
| %META{"attachments"}% | FileAttachment table | 
| %META{"parent"}% | The topic parent | 
| %EDITTOPIC% | Edit link | 
| %REVTITLE% | The revision title, if any, ex: (r1.6) | 
| %REVINFO% | Revision info, ex: r1.6 - 24 Dec 2002 - 08:12 GMT - TWikiGuest | 
| %WEBCOPYRIGHT% | Copyright notice, defined in the WebPreferences | 
| %BROADCASTMESSAGE% | Broadcast message at the beginning of your view template, can be used to alert users of scheduled downtimes; is defined in TWikiPreferences | 
 The "Go" Box and Navigation Box 
The 
%WEBTOPICLIST% includes a "Go" box to jump to a topic. The box also understand URLs, e.g. you can type 
http://www.google.com/
 to jump to an external web site. The feature is handy if you build a skin that has a select box of frequently used links, like Intranet home, employee database, sales database and such. A little JavaScript gets into action on the onSelect method of the select tag to fill the selected URL into the "Go" box field, then submits the form.
Here is an example form that has a select box and the "Go" box for illustration purposes. You need to have JavaScript enabled for this to work:

A skin can be activated in two ways:

The 
?skin=name URL parameter overrides the SKIN Preference value.
