You can use JavaScript and CSS to customize the behavior and screen appearance of an app.

You can create JavaScript programs using APIs.
For details on how to customize an app using JavaScript and CSS, refer to Kintone Developer Program.

This section describes how to upload created JavaScript and CSS files to an app.
Note that JavaScript and CSS files can be uploaded on Kintone only by Kintone Administrators.

JavaScript and CSS files can be uploaded for PCs and mobile devices (including the smartphone app) separately. The uploaded files are applied to the following screens of the app:

• The "View" screen
• The "Add Record" screen
• The "Edit Record" screen
• The "Record Details" screen
  Note that the files are also applied to the "Record Details" screen that is displayed when a record is opened via a notification from the app.
• The screen to print a record
• Tables and charts that present aggregate record data
  Note that the files are not applied to charts that are embedded in external sites by embed tags.
• The aforementioned screens in the app's test environment (only for PC)

1. Click the App Settings button at the upper right of the "View" screen, select the App Settings tab, and then select JavaScript and CSS Customization under Customization and Integration.
