FullCallendar - how to get rid of scrollbars?

Question

JavaScript

Good afternoon. The project uses FullCalendar. It is assumed that the site will be accessed from a mobile phone.
If you reduce the browser window (to simulate a mobile phone), scrollbars appear.

Googled that the parameters height: auto, contentHeight: auto, - should remove the scrollbars, but in fact nothing changes.

Can you tell me how to remove scrollbars?

Code example:

<div class="row">


    <div class="col-md-8 col-md-offset-2">
            <div class="panel panel-default">
                <div class="panel-body">
                    <div id="calendar"></div>



                </div>
            </div>
        </div>
</div>
