## Controls
You already know controls - the zoom control in the top left corner, the scale at the bottom right, the layer switcher at the top right. At their core, a `L.Control` is a HTML Element which is at a static position in the map container.
You already know controls - the zoom control in the top left corner, the scale at the bottom left, the layer switcher at the top right. At their core, an `L.Control` is an HTML Element that is at a static position in the map container.
To make a control, simply inherit from `L.Control` and implement `onAdd()` and `onRemove()`. These methods work in a similar way to their `L.Layer` counterparts (they run whenever the control is added to or removed from the map), except that `onAdd()` must return the instance of `HTMLElement` that represents the control - adding it to the map is done automatically, and so it's removing it.

If you custom control has interactive elements such as clickable buttons, remember to use `L.DomEvent.on()` inside `onAdd()` and `L.DomEvent.off()` inside `onRemove()`.
If your custom control has interactive elements such as clickable buttons, remember to use `L.DomEvent.on()` inside `onAdd()` and `L.DomEvent.off()` inside `onRemove()`.
If your custom control consists of more than one HTML element (like `L.Control.Zoom`, which has two buttons), you'll have to create the whole hierarchy of elements and return the topmost container.
