Customizing the Django admin interface
======================================
Django's dynamic admin interface gives you a fully-functional admin for free
with no hand-coding required. The dynamic admin is designed to be
production-ready, not just a starting point, so you can use it as-is on a real
site. While the underlying format of the admin pages is built in to Django, you
can customize the look and feel by editing the admin stylesheet and images.
Here's a quick and dirty overview some of the main styles and classes used in
the Django admin CSS.
Modules
=======
The ``.module`` class is a basic building block for grouping content in the
admin. It's generally applied to a ``div`` or a ``fieldset``. It wraps the content
group in a box and applies certain styles to the elements within. An ``h2``
within a ``div.module`` will align to the top of the ``div`` as a header for the
whole group.
Column Types
============
The base template for each admin page has a block that defines the column
structure for the page. This sets a class on the page content area
(``div#content``) so everything on the page knows how wide it should be. So far
there are three options available, and one special hybrid option.
colM
This is the default column setting for all pages. The "M" stands for "main".
Assumes that all content on the page is in one main column
(``div#content-main``).
colMS
This is for pages with one main column and a sidebar on the right. The "S"
stands for "sidebar". Assumes that main content is in ``div#content-main``
and sidebar content is in ``div#content-related``. This is used on the main
admin page.
colSM
Same as above, with the sidebar on the left. The source order of the columns
doesn't matter.
colM superwide
This is for ridiculously wide pages. Doesn't really work very well for
anything but colM. With superwide, you've got 1000px to work with. Don't
waste them.
flex
This is for liquid-width pages, such as changelists. Currently only works
with single-colum pages (does not combine with ``.colMS`` or ``.colSM``).
Form pages should never use ``.flex``.
For instance, you could stick this in a template to make a superwide page::
{% block coltype %}colM superwide{% endblock %}
or this to make a liquid-width page (note that ``flex`` replaces ``colM``, so
both classes are not required)::
{% block coltype %}flex{% endblock %}
Widths
======
There's a whole mess of classes in the stylesheet for custom pixel widths on
objects. They come in handy for tables and table cells, if you want to avoid
using the ``width`` attribute. Each class sets the width to the number of pixels
in the class, except ``.xfull`` which will always be the width of the column
it's in. (This helps with tables that you want to always fill the horizontal
width, without using ``width="100%"`` which makes IE 5's box model cry.)
**Note:** Within a ``.flex`` page, the ``.xfull`` class will ``usually`` set
to 100%, but there are exceptions and still some untested cases.
Available width classes::
.x50 .x75 .x100 .x150 .x200 .x250 .x300 .x400 .x500 .xfull
Text Styles
===========
Font Sizes
----------
Most HTML elements (headers, lists, etc.) have base font sizes in the stylesheet
based on context. There are three classes are available for forcing text to a
certain size in any context.
small
11px
tiny
10px
mini
9px (use sparingly)
Font Styles and Alignment
-------------------------
There are also a few styles for styling text.
.quiet
Sets font color to light gray. Good for side notes in instructions. Combine
with ``.small`` or ``.tiny`` for sheer excitement.
.help
This is a custom class for blocks of inline help text explaining the
function of form elements. It makes text smaller and gray, and when applied
to ``p`` elements withing ``.form-row`` elements (see Form Styles below), it will
offset the text to align with the form field. Use this for help text,
instead of ``small quiet``. It works on other elements, but try to put the class
on a ``p`` whenever you can.
.align-left
It aligns the text left. Only works on block elements containing inline elements.
.align-right
Are you paying attention?
.nowrap
Keeps text and inline objects from wrapping. Comes in handy for table headers you want to stay
on one line.
Floats and Clears
-----------------
float-left
floats left
float-right
floats right
clear
clears all
Object Tools
============
Certain actions which apply directly to an object are used in form and
changelist pages. These appear in a "toolbar" row above the form or changelist,
to the right of the page. The tools are wrapped in a ``ul`` with the class
``object-tools``. There are two custom tool types which can be defined with an
additional class on the ``a`` for that tool. These are ``.addlink`` and
``.viewsitelink``.
Example from a changelist page::
<ul class="object-tools">
<li><a href="/stories/add/" class="addlink">Add story</a></li>
</ul>
and from a form page::
<ul class="object-tools">
<li><a href="/history/303/152383/">History</a></li>
<li><a href="/r/303/152383/" class="viewsitelink">View on site</a></li>
</ul>
Form Styles
===========
Fieldsets
---------
Admin forms are broken up into groups by ``fieldset`` elements. Each form fieldset
should have a class ``.module``. Each fieldset should have a header ``h2`` within the
fieldset at the top (except the first group in the form, and in some cases where the
group of fields doesn't have a logical label).
Each fieldset can also take extra classes in addition to ``.module`` to apply
appropriate formatting to the group of fields.
.aligned
this will align the labels and inputs side by side on the same line.
.wide
used in combination with ``.aligned`` to widen the space available for the labels.
Form Rows
---------
Each row of the form (within the ``fieldset``) should be enclosed in a ``div``
with class ``form-row``. If the field in the row is required, a class of
``required`` should also be added to the ``form-row div``.
Labels
------
Each form ``label`` and field should be enclosed in a header ``h4``. Any
explanation or help text should follow this ``h4`` in a ``p`` with class
``.help``. Form labels should always precede the field, except in the case
of checkboxes and radio buttons, where the ``input`` should come first.
