Look and Feel

• All pages should be viewable on any browser that supports images, tables and forms. Browser features such as frames, DHTML, Javascript or Java should not be used unless there is no other option. It should be possible to use Webmin from browsers such as Netscape 1.1 or Pocket IE.

• All CGI programs that generate HTML output should call the header() function. The standard modules use 50-point helvetica text in black with a transparent background, created using The GIMP. Your modules should use the same font, size and style for consistency.

• The header() function outputs HTML tags setting the background, text and link colours for the generated page based on configured colour scheme. The init_config() function sets the global variables $tb and $cb which should be used as the background colour for table headers and body rows respectively, as in this example :

  print "<table border width=100%>\n";
  print "<tr $tb> <td><b>Foo</b></td> <td><b>Bar</b></td> </tr>\n";
  print "<tr $cb> <td>some value</td> <td>another value</td> </tr>\n";
  ...
  

• Try to avoid generating HTML forms that contain a large number of input fields. Some browsers (particularly netscape on Unix) slow down when rendering such pages.
