What you'll need
A mask is a vector shape that you use to hide parts of other content. The shape that is to become the mask must be on top of the content that you will mask.
Mask the content
- To apply a mask, select the shape to be used as a mask and the content to be masked.
- Choose Object > Clipping Mask > Make. The selected content becomes a clip group.
Edit the mask or content
- To edit the mask or the content being masked, with the clip group selected, click the Edit Clipping Path button or the Edit Contents button at the top of the Properties panel.
Another method for editing either the mask or masked content is to double-click on the clip group with the Selection tool selected to enter Isolation mode. Then select the mask and the content separately.
