Shadows and Inner Shadows appear as separate sections in the Inspector. They have the same controls but work in different ways — Shadows render outside a layer, while Inner Shadows render inside.
You can apply shadows to shapes, text, frames, graphics, and groups. You can also apply multiple shadows to the same layer and control their colors, blending modes, X and Y positions, blur radius, and spread.
In groups you can only apply one shadow, and it applies to the layers inside the group, not to the group itself.
Adding and removing shadows
Select a layer, frame, or group, then head to the Shadows or Inner Shadows section in the Style panel of the Inspector. Click 
to add a shadow.
To remove a shadow, disable its toggle switch, then click 
next to the section title.

Shadow controls
Each shadow has these controls:
- X and Y offset the shadow from the layer and can be positive or negative.
- Blur sets the blur radius in pixels.
- Spread (+ or -) sets the distance in pixels to expand or contract the shadow in all directions.
