When beginning any kind of Drupal development, you’ll need to be well-versed in best Drupal practices for customizing the look and feel of a Drupal site. However, you can also modify the appearance of your Drupal site without requiring expert knowledge of Drupal programming. You also have the open-source Drupal community available to ask and answer any questions you might have, as well as help you smooth out any speed bumps you might hit along the way.
Performing basic drupal development assumes some knowledge of HTML and Drupal CSS but no PHP Drupal programming knowledge is necessary (at first). It also assumes you have administrator’s privileges to a Drupal site. Start your drupal development by customizing the appearance and utilizing an existing theme. It can be surprising how customizable an existing theme can be by simply changing a few settings. There are also ways to make your own theme based on an existing theme, and you can always tweak your custom theme through the use of Drupal CSS stylesheets.
You’ll want to make sure to explore how to override various theme’s parts; regions and node types in case you need to use any of those skills in future Drupal development. Although it seems difficult, you can also easily create your own theme from scratch. If you would like to go farther with your Drupal development, you can begin exploring more advanced topics like employing PHP Drupal coding.
Using preferred techniques in the Drupal community is the best way to go. That way, if you run into any problems with your Drupal development, you have plenty of support solutions available at your fingertips. Drupal’s preferred theming engine and best practices involves copying files and modifying the copies, and overriding files with your own versions rather than editing the originals and housing all your modified theme’s files under the sites/all/themes directory. This is a positive step towards upgrade-proofing your site and facilitates future maintenance for your Drupal development project.
