During the initial installation of Drupal 7, you were never asked for a slogan; however you can easily add one. A slogan is a basic tagline for your website. Adding a slogan is easily accomplished through your dashboard.
To add a slogan to a page in Drupal 7:
- Log into your Drupal 7 Dashboard
- Go to Configuration
- Click on Site Information, located under the System category.
- Find the field labeled Slogan and type in your subtitle, or tagline.
- Click the Save configuration button once you are finished. Below is an example of how a slogan, or subtitle appears on your site. It is just under the main title.
