+
+Every widget can be selected using a `kebab-case` class name matching its name. 
+You can also target popups by prefixing `popup-` to the name. For example, you can use `.clock` and `.popup-clock` respectively.
+
+Setting the `name` option on a widget allows you to target that specific instance using `#name`. 
+You can also add additional classes to re-use styles. In both cases, `popup-` is automatically prefixed to the popup (`#popup-name` or `.popup-my-class`).
+
+You can also target all GTK widgets of a certain type directly using their name. For example, `button:hover` will select the hover state on *all* buttons.
+These names are all lower case with no separator, so `MenuBar` -> `menubar`.
+
+GTK CSS does not support custom properties, but it does have its own custom `@define-color` syntax which you can use for re-using colours:
+
+```css
+@define-color color_bg #2d2d2d;
+
+box, menubar {
+    background-color: @color_bg;
+}
+```
