Views

A site asset may be viewed in various ways, depending on the type of asset:

Source view displays the code that is in the content file associated with the site asset: HTML, XML, JavaScript, Idoc Script, Site Studio tags, and so on. See Source View for more information.
Design view displays all objects as they are arranged on a site template, both static (for example, a fixed banner graphic) and dynamic (placeholders and fragments). See Design View for more information.
Preview provides an actual view of a site template with all assets in place, as it appears to site consumers in a web browser. See Preview for more information.
Form view provides a dialog in which you can set the properties of a site asset. See Form View for more information.

View Tabs in Workspace

You can use the arrows in the bottom-left corner of the workspace to move between the views of the current site asset. By default, site templates open in design view, while definition assets open in form view. Most other assets (for example, contributor data files and CSS files) open in source view. Native documents open in their associated third-party application.
