-<WRAP info>
+<WRAP important>
-**NOTE:**  The code in **prefs.js** will be executed in a separate Gtk process.
+**WARNING:**  Some properties may only be available in some versions of GNOME Shell.
-  * Here you will not have access to code running in GNOME Shell, but fatal errors or mistakes will be contained within that process.
+  * All properties should be considered read-only.
-  * In this process you will be using the Gtk toolkit, not Clutter.
-  * You can open the preferences dialog for your extension manually with gnome-extensions prefs: <code bash>

-===== stylesheet.css =====
-**stylesheet.css** is CSS stylesheet which can apply custom styles to your St widgets in extension.js or GNOME Shell as a whole.
-For example, if you had the following widgets:
-<code javascript>
-// A standard StLabel
-let label = new St.Label({
-    text: 'LabelText',
-    style_class: 'example-style'
-});
-// An StLabel subclass with `CssName` set to "ExampleLabel"
-var ExampleLabel = GObject.registerClass({
-    GTypeName: 'ExampleLabel',
-    CssName: 'ExampleLabel'
-}, class ExampleLabel extends St.Label {
-});
-let exampleLabel = new ExampleLabel({
-    text: 'Label Text'
-});
-</code>
-You could have this in your stylesheet.css:
-<code css>
-/* This will change the color of all StLabel elements */
-StLabel {
-    color: red;
-}
-/* This will change the color of all elements with the "example-style" class */
-.example-style {
-    color: green;
-}
-/* This will change the color of StLabel elements with the "example-style" class */
-StLabel.example-style {
-    color: blue;
-}
-/* This will change the color of your StLabel subclass with the custom CssName */
-ExampleLabel {
-    color: yellow;
-}
-</code>
