Adding shape element
There are many uses for adding a shape element. You can cover a portion of the screen, darken an image behind the overlay, and so much more.
The 'Shape Element ' is located on the left side of the dashboard, underneath the 'Text Element.'
Click on the button and the default gradient shape will appear.
Click on the 'Gradient' to change to 'Color.' For this experience, I am going to choose the color black and stretch the element to cover the entire screen.
In order to be able to see the background image, you will need to decrease the opacity.
You can also use the shape to cover part of the background image.
