Optical illusions are one of the favorite moves of designers and artists. They help to attract attention both to the design of the room, the image in the picture, and to the content of the site, to diversify the interface on any device. Today we will tell you about one such trick called the parallax effect. Let's start with its definition.
What is parallax?
Parallax (Greek παραλλάξ - "alternation", "change of something") - this is the name of the change in the apparent position of the object in relation to the distant background, depending on the location of the observer.
It is on this phenomenon that binocular vision is based - the ability to clearly distinguish one image, while looking with two eyes. In astronomy and geodesy, the parallax effect is used to measure distances to distant objects.
