Full control over Design an Markup

There is nothing worse than a CMS deciding what markup you should use. That's why we give you 100% control over templating and output, with no limitations to your design.

CSS Control

We think editors are happier focusing on producing great content, not worrying about layout. Adding design guidelines for your editors to follow will allow you to specify which CSS rules your editors can use in the built-in wysiwyg editor, with human-friendly names you control. "Big Old Headline" makes a lot more sense to an editor than H1 right? And you can rest easy, knowing they're not destroying your design.

Javascript unlimited

Javascript is a huge part of the web today and Umbraco gives you full control. Create and organize your scripts. Make asynchronous applications. Extend the backoffice. No limitations! And as always you can use the backoffice or your favourite editor.

Starter Kits & Skins

Our starter kits take you from 0-to-done in minutes. These simple website starter kits let you install a site with great markup and apply a skin with great design. You can even change the default if you're feeling a bit creative.

Use your Favourite Editor

Using your editor of choice is easy, be it Visual Studio, WebMatrix, Notepad++, Dream Weaver or any other to modify your website. Or, if you prefer you can use our integrated web-based editor.
