Drop Shadow

Hi @MahaB82A, select the shadow shape you'd like to adjust. Click on the gradient icon (left toolbar). Hover over the right black node (as shown in the image I've attached) until you see the little "scale" icon. Click and drag toward the center of your shadow shape and this will scale your gradient.

If you hover over the top node instead, you'll see an icon that allows you to compress the gradient shape.

You can also adjust your gradient sliders here.

Please share this sample Illustrator file for inspection.
