Thanks Antonio

But I guess it reveals my thin programming skills

I found the table cell in the Archive.ascx file, ID calMonth and reference to the “Normal class” for text formatting.

<td>
   <asp:calendar id="calMonth" runat="server" cssclass="Normal"></asp:calendar>
</td>

Can I change the "Normal Class" to "CalMonth Class" and add the font settings into the CalMonth Class?

If that works, it should just be to add the CalMonth Class in the default.css as below?

/* text style used for most text rendered by modules */
.Normal,.NormalDisabled
{
    font-family: Tahoma, Arial, Helvetica;
    font-size: 16px;
    font-weight: normal;
    color: #000000;

}

/* New CssClass for the calendar properties / width */

.calMonth
{
     font-family: Tahoma, Arial, Helvetica;
    font-size: 16px;
    font-weight: normal;
    color: #000000;

    CellPadding:
    CellSpacing:
    width: 75%;

}

Cheers…

PS. I tested the Width Property at 75% in the Normal Class but it wasn’t picked up?
