I always a very simple theme for the backend. I don't need any blocks there at all. And I don't even need a header or and other of this fancy corporate design stuff. I want space for my work. Thus the admin.htm is very short:
[code]
<?xml version="1.0" encoding="iso-8859-15"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="de" xml:lang="de">
<head>
</head>
<body>
[ Home | Administration | Statistics ]
</body>
</html>
[/code]
That's it.
Done - Your new lean backend layout will always appear when functions are called via admin.php (old-style) or with type=admin within the URL.
We will have a small problem with pagesetter. As it doesn't have a clearly defined backend there's no type=admin in the URL. I always use a small "Pagesetter fix" in my master.htm:
I hope this article helps you implement a better backend with much space.
