CSS Background Blending should be performed, regardless the background layer possible combinations.
As a first step of validating the feature, tests should be added for the following use cases:

1. Bg blend mode for an element with just one image as the background.
2. Bg blending for an image and a background color. Different background images should be tested, having different formats, such as png or jpg.
3. Bg blending for a gradient and a background color.
4. Bg blending for a gradient on top of an image.
5. Bg blending for an image on top of a gradient.
6. Bg blending for a gradient on top of another gradient. 
7. Bg blending for an image on top of another image. 
8. Bg blending for an image on top of a background color. 
9. Blend multiple background layers (3 images, for example).
10. Blend 3 background images, specify less blend modes in CSS.
11. Change the background blending mode of an element from script.
