Added admin browser support policy note.

like to make should be possible by editing the stylesheet. We've got a

:doc:`guide to the CSS used in the admin </obsolete/admin-css>` to get you started.

What browsers are supported for using the admin?

------------------------------------------------

The admin provides a fully-functional experience to `YUI's A-grade`_ browsers,

with the notable exception of IE6, which is not supported.

There *may* be minor stylistic differences between supported browsers—for

example, some browsers may not support rounded corners. These are considered

acceptable variations in rendering.

We've switched the admin and other bundled templates to use the HTML5

doctype. While Django will be careful in its use of HTML5 features, to maintain

compatibility with old browsers, this change means that you can use any HTML5

compatibility with older browsers, this change means that you can use any HTML5

features you need in admin pages without having to lose HTML validity or

override the provided templates to change the doctype.

Supported browsers for the admin

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Django hasn't had a clear policy on which browsers are supported for using the

admin app. Django's new policy formalizes existing practices: `YUI's A-grade`_

browsers should provide a fully-functional admin experience, with the notable

exception of IE6, which is no longer supported.

Released over ten years ago, IE6 imposes many limitations on modern web

development. The practical implications of this policy are that contributors

are free to improve the admin without consideration for these limitations.

This new policy **has no impact** on development outside of the admin. Users of

Django are free to develop webapps compatible with any range of browsers.
