    The read-only styleSheet property of the
+	{{domxref("CSSImportRule")}} interface returns the CSS Stylesheet specified by the
+	{{cssxref("@import")}} at-rule. This will be
+	in the form of a {{domxref("CSSStyleSheet")}} object.
    
+
+
    An {{cssxref("@import")}} at-rule always has
+	an associated stylesheet.
    
+
+
    Syntax
    
+
+
    var href = CSSImportRule.styleSheet;
    
+
+
    Value
    
+
    A {{domxref("CSSStyleSheet")}}.
    
+
+
    Examples
    
+
+
    The following stylesheet includes a single {{cssxref("@import")}} rule. Therefore the
+	first item in the list of CSS rules will be a CSSImportRule. The
+	styleSheet property returns the imported stylesheet.
    
+
+
    @import url("style.css") screen;
    
+
+
    let myRules = document.styleSheets[0].cssRules;
+console.log(myRules[0].styleSheet); //returns a CSSStyleSheet object

    The following code is taken from my Gamepad API button demo (you can view the demo live, and find the source code on Github.) Note the code fork — in Chrome {{domxref("Navigator.getGamepads")}} needs a webkit prefix and the button values are stored as an array of double values, whereas in Firefox {{domxref("Navigator.getGamepads")}} doesn't need a prefix, and the button values are stored as an array of {{domxref("GamepadButton")}} objects; it is the {{domxref("GamepadButton.value")}} or {{domxref("GamepadButton.pressed")}} properties of these we need to access, depending on what type of buttons they are. In this simple example I've just allowed either.

    Notes
    
 
 
    When an error occurs in a script, loaded from a different origin, the details of the error are not reported to prevent leaking information (see {{bug("363897")}}). Instead the error reported is "Script error." This behavior can be overridden in some browsers using the {{htmlattrxref("crossorigin","script")}} attribute on {{HTMLElement("script")}} and having the server send the appropriate CORS HTTP response headers.  A workaround is to isolate "Script error." and handle it knowing that the error detail is only viewable in the browser console and not accessible via JavaScript.
