    87== Project Logo and Icon
     8The easiest parts of the Trac interface to customize are the logo and the site icon. Both of these can be configured with settings in [TracIni#project-section trac.ini].

    10 The 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].
     10The logo or icon image should be put your environment's `htdocs` directory. 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.
    1111
    12 The 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''.

    14 '''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.

    20 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'.

    3226Icons 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:

     34The `[mainnav]` and `[metanav]` sections of trac.ini be used to customize the navigation items' text and link, or even disable them, but not for adding new ones.

    86 Notice that XSLT bears some similarities with Genshi templates. However, there are some Trac specific features, for example the `${href.chrome('site/style.css')}` attribute references `style.css` in the environment's `htdocs/` directory. In a similar fashion `${chrome.htdocs_location}` is used to specify the common `htdocs/` directory belonging to a Trac installation. That latter location can however be overriden using the [[TracIni#trac-section|[trac] htdocs_location]] configuration setting.

    88 `site.html` is one file to contain all your modifications. It usually works using the `py:match` directive (element or attribute), and it allows you to modify the page as it renders. The matches hook onto specific sections depending on what it tries to find and modify them.
    89 See [http://groups.google.com/group/trac-users/browse_thread/thread/70487fb2c406c937/ this thread] for a detailed explanation of the above example `site.html`.
    90 A `site.html` can contain any number of such `py:match` sections for whatever you need to modify. This is all Genshi, so the [http://genshi.edgewall.org/wiki/Documentation/xml-templates.html docs on the exact syntax] can be found there.

    103 This example illustrates a technique of using `req.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.path_info == '/timeline'` condition in `<py:if>` test.

    109 If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can be loaded using a workaround, provided it contains no [trac:ClearSilver] processing. In addition, as only one element can be imported, the content needs a 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:
    110 {{{#!xml
    111 <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')"
    112         xmlns:xi="http://www.w3.org/2001/XInclude">
    113   <py:if test="req.path_info == '/newticket' and (not 'preview' in req.args)">
    114     <xi:include href="site_newticket.cs"><xi:fallback /></xi:include>
    115   </py:if>
    116   ${select('*')}
    117 </form>
    118 }}}
    119 
    120 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 maintenance (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.

    189170The 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 whenever possible, see [#SiteAppearance]. 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.
    190171
    191 With that word of caution, any Trac template may be copied and customized. The default Trac templates are located inside the installed Trac egg, such as `/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.

    194175 * For a modification to one project only, copy the template to project `templates` directory.
    195  * For a modification shared by several projects, copy the template to a shared location and have each project point to this location using the `[inherit] templates_dir` trac.ini option.
