Step 1: After you log in, click on Calendars (brown box below).

The Your Calendars page will open.

Step 2: Choose the card view calendar you wish to modify. In this case, you can choose a cards (list) or (grid) view option (brown box below).

Step 3: Click on Design (brown box below).

Step 4: Scroll down and click on Frame and cells (brown box below).

Step 5: Scroll down until you find Card left and right margin.

This design element controls how much space is to the left and right of the cards themselves.

Compare a 5% margin (brown box and gold arrows in the image above) with a 15% margin (brown box and gold arrows in the image below). As you can see, the width and length of the cards change to accommodate the new margin.

To change the percent of space, simply type a number on the relevant line.

Click Save at the bottom to save your changes.
