    85This page gives suggestions on how to customize the look of Trac. Topics include editing the HTML templates and CSS files, but not the program code itself. The topics show users how they can modify the look of Trac to meet their specific needs. Suggestions for changes to Trac's interface applicable to all users should be filed as tickets, not listed on this page.

    107== Project Logo and Icon
    11 
    128The easiest parts of the Trac interface to customize are the logo and the site icon. Both of these can be configured with settings in [wiki:TracIni trac.ini].
    139
    1410The logo or icon image should be put in a folder named "htdocs" in your project's environment folder. ''Note: in projects created with a Trac version prior to 0.9 you will need to create this folder''.
    1511
    16  '''Note''': you can actually put the logo and icon anywhere on your server (as long as it's accessible through the web server), and use their absolute or server-relative URLs in the configuration.

    2016=== Logo
    21 
    22 Change the `src` setting to `site/` followed by the name of your image file. The `width` and `height` settings should be modified to match your image's dimensions. The Trac chrome handler uses "`site/`" for files within the project directory `htdocs`, and "`common/`" for the common `htdocs` directory belonging to a Trac installation. Note that 'site/' is not a placeholder for your project name, it is the literal prefix that should be used. For example, if your project is named 'sandbox', and the image file is 'red_logo.gif' then the 'src' setting would be 'site/red_logo.gif', not 'sandbox/red_logo.gif'.

    3227=== Icon
    33 
    3428Icons are small images displayed by your web browser next to the site's URL and in the `Bookmarks` menu. Icons should be a 32x32 image in `.gif` or `.ico` format. Change the `icon` setting to `site/` followed by the name of your icon file:

    4135== Custom Navigation Entries
    42 
    4336The new [mainnav] and [metanav] can now be used to customize the text and link used for the navigation items, or even to disable them, but not for adding new ones.
    4437
     
    5548See also TracNavigation for a more detailed explanation of the mainnav and metanav terms.

    5952Trac is using [http://genshi.edgewall.org Genshi] as the templating engine. Say you want to add a link to a custom stylesheet, and then your own header and footer. Save the following content as `site.html` inside your projects `templates/` directory (each Trac project can have their own `site.html`), eg `/path/to/env/templates/site.html`:
     
    9689{{{#!xml
    9790<form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')">
    98   <py:if test="req.environ['PATH_INFO'] == '/newticket' and (not 'preview' in req.args)">
     91  <py:if test="req.path_info == '/newticket' and (not 'preview' in req.args)">
    9992    <p>Please make sure to search for existing tickets before reporting a new one!</p>
    10093  </py:if>
     
    10396}}}
    10497
    105 This example illustrates a technique of using `req.environ['PATH_INFO']` to limit scope of changes to one view only. For instance, to make changes in `site.html` only for timeline and avoid modifying other sections - use  `req.environ['PATH_INFO'] == '/timeline'` condition in `<py:if>` test.

    111 If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can be loaded using a workaround - providing it contains no [trac:ClearSilver] processing. In addition, as only one element can be imported, the content needs some sort of wrapper such as a `<div>` block or other similar parent container. The XInclude namespace must be specified to allow includes, but that can be moved to document root along with the others:
    112 {{{#!xml
    113 <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')"
    114         xmlns:xi="http://www.w3.org/2001/XInclude">
    115   <py:if test="req.environ['PATH_INFO'] == '/newticket' and (not 'preview' in req.args)">
    116     <xi:include href="site_newticket.cs"><xi:fallback /></xi:include>
    117   </py:if>
    118   ${select('*')}
    119 </form>
    120 }}}
     104Note that the `site.html`, despite its name, can be put in a shared templates directory, see the [[TracIni#inherit-section|[inherit] templates_dir]] option. This could provide easier maintainence as one new global `site.html` file can be made to include any existing header, footer and newticket snippets.

    122 Also note that the `site.html`, despite its name, can be put in a shared templates directory, see the [[TracIni#inherit-section|[inherit] templates_dir]] option. This could provide easier maintainence (and a migration path from 0.10 for larger installations) as one new global `site.html` file can be made to include any existing header, footer and newticket snippets.

    128110The following is the basic template used by Trac to display a list of links to the projects. For projects that could not be loaded, it displays an error message. You can use this as a starting point for your own index template:

    181163   {{{#!sh

    189171== Project Templates
    190172
    191 The appearance of each individual Trac environment, ie instance of a project, can be customized independently of other projects, even those hosted on the same server. The recommended way is to use a `site.html` template (see [#SiteAppearance]) whenever possible. Using `site.html` means changes are made to the original templates as they are rendered, and you should not normally need to redo modifications whenever Trac is upgraded. If you do make a copy of `theme.html` or any other Trac template, you need to migrate your modifiations to the newer version. If not, new Trac features or bug fixes may not work as expected.

    193 With that word of caution, any Trac template may be copied and customized. The default Trac templates are located inside the installed Trac egg (`/usr/lib/pythonVERSION/site-packages/Trac-VERSION.egg/trac/templates, .../trac/ticket/templates, .../trac/wiki/templates, ...`). The [#ProjectList] template file is called `index.html`, while the template responsible for main layout is called `theme.html`. Page assets such as images and CSS style sheets are located in the egg's `trac/htdocs` directory.
