Sharepoint Designer 2013

SharePoint page-design features

The following feature is not available in SharePoint 2013.

Design view and Split view

Description of the change.SharePoint Designer 2010 has three views for editing HTML and ASPX pages: Code view, Design view, and Split view. Design view and Split view are removed from SharePoint Designer 2013. The removal of Design view and Split view affects the features of SharePoint Designer 2013 that are used for editing Web Parts and master pages. If you edit pages in SharePoint Designer 2013, you must use Code view.

Reason for the change. Compared to current versions of Internet Explorer, Design view is an older technology that does not support many new HTML5 and CSS tags.

Migration path. If you edit pages in Code view, you can press F12 to preview the page in the browser. Alternatively, you can use Visual Studio to edit pages.

If you want to visually design or brand your site, and you want a WYSIWYG ("what you see is what you get") page-editing experience, you can use any professional HTML editor, such as Microsoft Expression Web. Then you can import your HTML files into SharePoint Server 2013 by using the new Design Manager, which is a feature included in publishing sites, such as the Publishing Portal Site Collection site template.
