        <video id="video"></video>
        <div class="CUvideoside">
            <a id="button">Camera button</a>
            <!-- target for the canvas-->
            <div id="canvasHolder"></div>
            <!--preview image captured from canvas-->

            <div class="CUdone">
                <a href="javascript:void(0);">Done</a>

    -o-user-select: none;
    user-select: none;
    -webkit-touch-callout: none;
}
