Drupal gives you complete control of your content presentation
Drupal's presentation layer allows designers to create highly usable, interactive experiences that engage users and increase traffic. Drupal themes can range from simple to complex, and support rich customization. Use an existing Drupal theme for your site to give it an instant polished look! If you can't find one you like, try designing your own that others can use, too.
Drupal’s themes give you the option of choosing to use either the default regions or customizing your own. Within these regions you can place blocks for content relevant to your site, including menus or custom blocks for widgets. Drupal’s themes are also designed with the principles of accessibility in mind: easy navigation, clear headings, logical page structure, and much more.
Views — opening up more possibilities
Views plugins can also be useful tools for designers. With Views Slideshow, you can display items such as photos and text in your view as a slideshow. Views Accordion, another display-oriented plugin, allows you to display content that opens up when the header is clicked. Semantics Views makes design more accessible to site builders and other end users by giving them an easier way to customize and configure themes.
jQuery and jQuery UI integration
Drupal's tight integration with jQuery and jQuery UI lets you push the boundaries of user experience. The BeautyTips module integrates the BeautyTips jQuery tooltip plugin to create rollover help balloons for any element on your page, while the Calendar module Date Popup creates pop-up calendars in a form for users to select specific dates. Choose from hundreds of JavaScript modules to make your site more modern and user-friendly.
Usability and accessibility in Drupal
Drupal is a well-tooled system that is easy to set up and highly configurable for designers and administrators, and so intuitive that even users with minimal prior experience can easily navigate sites. Researchers have conducted usability studies at research centers such as the University of Baltimore and the University of Minnesota, and based on those studies, the community has made many user interface and workflow improvements in Drupal 7. Drupal also has modules that continue to improve usability: the Better Formats module adds more flexibility to Drupal's core input format system, and the Admin Role module and Admin Menu module can make administration even easier and faster.
Drupal strives to empower all site builders, and efforts to make the web accessible to people with disabilities will always be a vital part of the project. Drupal core now has an official Accessibility Maintainer to ensure that Drupal is an accessible tool for both building websites and helping you create websites that are themselves accessible.
