how to change size of calendar in spiffy calendar

If you are referring to the full size calendar that is embedded in a page, the default size is 100% width. You can reduce this by adding some custom CSS like the following:

.spiffy.calendar-table {
max-width: 500px;
}

This would apply to both the full calendar and mini calendar.

Not real familiar with CSS but I added .spiffy.calendar-table {
max-width: 500px;
}
to the end of the code for the calendar and got a syntax error. Should I ‘place it osme where else?

You should add it in the space for custom CSS in the Spiffy Calendar Options area in the dashboard.

Thanks Works Great
