SilverStripe CMS & Framework features
The SilverStripe CMS is easy for both developers and content authors to work with. The SilverStripe Framework keeps the code tucked away neatly so that it can be accessed easily by programmers without getting in the way of content authors.
An out-of-the-box installation of the SilverStripe CMS provides all the day-to-day editing control you are likely to need as a content author. With WYSIWYG and drag & drop functions, site editors have full control over the way they want their content to look without needing to know HTML. If you can use a word processor, you can use the SilverStripe CMS. Images and files can be added through a drag & drop interface, and pages and templates are fully customisable. Themes and widgets allow even more extensions. Developers can further customise the interface to suit how you work as an author and as a business.
