+# Frequently Asked Questions
+
+## How do I use `z-index`?
+
+The z-index property isn't currently supported. We're trying to figure out the best API for layered elements, and you can help! Please submit your use cases to [issue #46](https://github.com/mdgriffith/style-elements/issues/46) so we can find the best solution for everyone.
+
+While you're waiting, you can use the [`Style.prop` function](http://package.elm-lang.org/packages/mdgriffith/style-elements/latest/Style#prop) to get what you need:
+
+```elm
+zIndex : Int -> Property class variation
+zIndex n =
+    prop "z-index" (toString n)
+```
+
+## How do I set margins?
+
+Supporting both margins and padding make consistent layouts difficult, so style-elements only uses padding.
+
+If you need spacing between children in a layout, use [`Element.Attributes.spacing`](http://package.elm-lang.org/packages/mdgriffith/style-elements/latest/Element-Attributes#spacing).
+
+To set more space around a single element, wrap the element in a spacer a set padding. This is more explicit and you can predict exactly how your element will be laid out.
