The position property figuring how an element placed in the window / browser. Visibility and display determine is an element visible or not. Size determine the size of an element. Opacity / filter determine if an element will be transparent or opaque.
Dynamic effects / animations can be achieved by manipulating that properties rightly. For example if we want placed an element overlap with another we can accomplish this task with position property. Want to make an element blur if an event happens? Opacity/filter will come to help us do this.
