## Mobile

Mapbox.js is optimized for mobile devices and small screens by default. There are, however, best practices to make sure your map always looks its best.

### Viewport

Modern mobile browsers now support scaling of webpages by leveraging the meta tag `viewport`. This enlarges the window making your map look better on a mobile device. Simply include this in the head of your document:

    <meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no' />

### Scrolling

If you're planning on having a page that has large amounts of scrolling, try to avoid a large map height. Having a 'tall' map can cause the user to get stuck on the map while scrolling. Another way around this is to disable `dragging` for mobile devices: `map.dragging.disable();`

### Retina

Having the ability to use retina tiles when the device supports them is easy. When creating the map, use the `detectRetina` to verify if retina is available and `retinaVersion` to use a tilelayer which is designed for retina screens.

    var map = L.mapbox.map('map', 'your.mapid', {
        tileLayer: {
            detectRetina: true,
            retinaVersion: 'your.mapid'
        }
    }).setView([40, -74.50], 9);

Some Mapbox maps support switching to retina scale automatically: if you're using one of these maps, you can simply set `detectRetina` and the higher-scale tiles will be used when retina is detected.

    var map = L.mapbox.map('map', 'your.mapid', {
        tileLayer: {
            detectRetina: true
        }
    }).setView([40, -74.50], 9);
