Calendar Extender Style

I would like to enlarge the Calendar Extender to 2 times. However, when I use the style like following:

    .ajax__calendar_container, .ajax__calendar_body, .ajax__calendar_days, .ajax__calendar_months, .ajax__calendar_years {
        width: 280px !important;
    }


    .ajax__calendar_container td {
        font-size: 22px !important;
        width: 34px;
        height: 34px;
    }

It only enlarges the width, the height cannot be enlarged. And when I click the Month, the month selection box cannot be enlarged 2 times.

Is there any methods to enlarge the whole control style 2 times directly?
