Once the custom theme ZIP is downloaded, it needs to be decompressed, the folder with the custom theme information found, and a jQuery UI file renamed for use within the Application Designer site.
1. Decompress the ZIP file and go into the decompressed folder.
2. Open the folder entitled “jquery-ui-1.10.x.custom”.
3. Open the css folder, then navigate into the folder with your theme’s name (from step 6).
4. Within the folder with the theme name, find the entitled “jquery-ui-1.10.x.custom.min.css”.
5. Make a copy of the “jquery-ui-1.10.x.custom.min.css” file and rename the copied file to “jquery-ui.css”.
