Custom template infoBox

Hello!
Please help me, how make custom style on infobox?

And change the position infobox, of the mouse cursor.

var marker = me.earth.entities.add({

position : Cesium.Cartesian3.fromDegrees(x, y),

billboard : {

image : ‘/img/icon.png’,

},

label : {

text : ‘Marker 1’,

font : ‘10pt monospace’,

style: Cesium.LabelStyle.FILL_AND_OUTLINE,

outlineWidth : 2,

verticalOrigin : Cesium.VerticalOrigin.TOP,

pixelOffset : new Cesium.Cartesian2(0, 32)

}

});

Thank you in advance !
