Design Guide for Fedora Infrastructure Web Applications
It is still under construction and content may change. Do not rely on the information on this page.
All Fedora Infrastructure Applications should be designed with a few common elements. These elements should share common css classes and ids to allow a common look and feel.
Menus and toolbars
Menus are represented as unordered lists. Each element in the menu is a <li>. It is recommended that the standard menus presented here stay at one or at most two levels. Menu items that are simply textual links do not need any special classes. Menuitems that are more dynamic (for instance, searchboxes, login buttons, and loginboxes) should have the class "toolitem". The <li> contains additional classes based on what they do:
- search-toolitem
- use this if they contain a widget to enter search terms.
- lang-toolitem
- Use this for a language selector box.
- login-toolitem
- Use this for something that allows a user to login.
For instance, for a button that takes the user to a login form, use:
<li class="toolitem login-toolitem">You are not logged in
<form action="/accounts/login" method="POST">
<input type="submit" value="Login" class="button" />
</form>
</li>
Preferences
- id
- prefbar
- id
- infobar(obsolete)
This menu is for user preferences and user-oriented information. It should include the entries for the user to login and logout of the application, information on the logged in state, language selection (if applicable), perhaps other simple preferences, and a link if needed for more complex preferences.
In the fedora stylesheet this is rendered as a single bar across the top of the page. It is best kept to a flat hierarchy (no nesting of lists).
- id
- extnav
- id
- topnav(obsolete)
The External Navigation is for items that are external to the application. For instance, links to the fedoraproject home page, documentation, instructions for joining fedora, the Fedora Account System, etc.
In the fedora stylesheet this is rendered as a single bar below the header. It is best kept to a flat hierarchy (no nesting of lists).
- id
- intnav
- id
- sidebar(obsolete)
This menu is for links internal to the application. In the fedora stylesheet, it is rendered as a menu along the side of the application. It can handle one nested level of hierarchy and still look okay:
<ul>
<li>User view
<ul>
<li>User packages</li>
<li>User friends</li>
</ul>
</li>
<li>Package Information
<ul>
<li>Builds</li>
<li>Updates</li>
</ul>
</li>
</ul>
Search boxes should appear as a <li> in this menu with the class "toolitem toolitem-searchbox"
Header
- id
- header
- id
- head(obsolete):
The header area is a banner across the top of a page. It contains information to visually identify the page as being part of Fedora and/or part of a specific web application. The header is the most specified area of this design document. It may contain the following classes:
- fedora_title
- This is logo and/or text pointing for Fedora. It will normally be rendered on the left side of the header area. It should be placed on an <h1> that contains a link to a main part of the fedoraproject.org website like this:
<h1 class="fedora_logo"><a href="http://fedoraproject.org/">Fedora</a></h1>
- The fedora stylesheet will place the Fedora Logo in place of the words inside of the <a> link. The link should point to something very highlevel like fedoraproject.org, fedoraproject.org/wiki/ or another major portal page. It should not point to a portal page relevant to the app itself. For that, use the app_title class
- app_title
- This is text and logos that reference the app itself. If this contains a link, it should reference the top level of the application (not a fedorahosted page for the app, etc). Use it like this:
<h1 class="app_title"><a href="https://admin.fedoraproject.org/community/">Fedora Community</a></h1>
- Apps which don't use this should contain a link to the application's top page in their Internal Navigation Bar (for instance, "Home"). The fedora stylesheet contains a simple rendering of this that sizes the text, removes the obvious link decorations and places it so that it will render alongside a fedora_title element if present. The application is free to override this in its own stylesheet to display a logo in its place. Applications which do the latter may want to forgo using fedora_title to avoid having two competing logos in the header.
Content
- id
- content
The content area should be the central and largest area of the app. It is where the application does most of its app-specific drawing. Nothing within the content area is specified here; the content area is entirely up to the application to use.
- id
- footer
The footer is the place for links that people don't normally need but may want to access if they have a special interest in meta-information about the project or software. This includes things like copyright and license information, the software's bug tracker and source code, and links to the same.
The following classes are recognized:
- copyright
- The software copyright holders and years
- (obsolete)copy
- same as above
- license
- The license information for the software (optional)
- version
- Version information for the software (optional)
- content_copyright
- Separate copyright information for the content (optional)
- content_license
- Separate license information for the content (optional)
- content_version
- Separate version information for the content (optional)
- disclaimer
- Any boilerplate legal disclaimers
- lhost
- Host that the app is running on (optional)
- powered_by
- Powered by logos (optional)
- sponsor
- Links and logos for sponsors (optional)
- footlinks
- An
- of links. If this is used, it should be a simple list of items. It might be rendered like this::
<center>About | Fedora Project | Contact Us | Legal</center>
Layout
In the Fedora stylesheet, these elements are laid out like this:
[ <======prefsbar|] ------------------------- | | | Header|===> | | | ------------------------- [ <===|extnav|===> ] ------------------------- | | | |intnav| content | | | | ------------------------- | | | <===|footer|===> | | |
Things specifically removed
- id
- wrapper This used to wrap around all of the body. Why not just use <body> instead?
