JavaScript Style Sheet File

  • Category Web Files
  • Format Text

File created in the JSS (JavaScript Style Sheets) format, an extension of the CSS language that supports multiple inheritance, whereas standard CSS only supports single inheritance; allows more flexibility when defining styles for webpages.

The JSS files must be parsed and converted to the .CSS format before they can be used with a webpage. Therefore, you need to use the jss program as shown in the following command, which converts styles.jss to styles.css:

jss styles.jss styles.css

NOTE: JSS files use the inherit-class:, inherit-id:, and inherit-tag: syntax in CSS definitions to provide for inheritance.
