/** @jsx createElement */

'use strict';

import { createElement, PropTypes, Component } from 'rax';
import { isWeex } from 'nuke-env';
import View from 'nuke-view';

const initStyle = { zIndex: 2, position: 'sticky', top: 0 };

class Header extends Component {

    }
    return <View style={[initStyle, style]} {...others} />;
