This tab displays the file content of the currently edited container's theme folder and allows it to be managed. The theme folder of a web part container is always located under the ~/App_Themes/Components/Containers/ directory and its name is the same as the code name of the container to which it belongs. The folder usually contains any files used by the CSS classes defined locally in the container's CSS styles property.

 

Detailed information about the actions available on this tab can be found in the File system dialog help topic.

 

Please note, only file formats commonly required by CSS stylesheets are displayed here. This includes the following: .css, .skin, .gif, .png, .bmp, .jpg
