For quite some time now, the website and the so-called "parallax" effect have been very popular. In case you haven't heard of this effect, different images are moved in different directions or layers are mainly included. This leads to a good optical effect that makes the visitor's attention.In web design, in order to implement this is a simple site to add a jquery plugin to the most common way. To do so, unfortunately, there are several drawbacks. The
