How is Drupal different from an HTML web site?

Drupal is different from an HTML website in that a person developing a Drupal site makes design and structural choices from menus rather than working directly in the HTML, CSS and JavaScript code. To a person visiting your site it will look or function as any other web site.

Drupal has many components which take time to master. As with HTML web sites, you may be able to create a simple site on your own.  As the complexity of your site increases so does the knowledge required to create it. At some point you may need to seek help from internal MIT or external Drupal developers. See the Resources link under the HELP menu for suggestions.
