A theme is a collection of files which together determine the look and feel of a drupal web site. Themes are available for free or a small price on the Internet.

Downloading Drupal Themes

Themes can be found at http://drupal.org/project/Themes. Suppose we want to download the art4 blue theme. Drupal themes and modules are available as zipped tar files. On Unix, you do the following:

$ wget http://the-site/theme.tar.gz
$ tar -xzvf theme.tar.gz
$ rm theme.tar.gz

On windows, download http://www.7-zip.org/. This free tool works with several unix specific zipped files. I have installed cygwin, which allows me to run unix command-line tools on my windows machine.

Installing Themes

Once you have extracted the files, you need to upload the folder into the themes folder. I use fireftp to upload files. It is very neat firefox plugin.

Once you have uploaded your files, they should become visible in the list of themes:

Administer > Site building > Themes

Click on the radio button and checkbox to the right of your new theme and click on save configuration.

Deleting Themes

To delete a theme, just delete its folder from the theme.
