Parallax
                    Parallax is an effect where the background content or image in this case, is moved at a different speed than the foreground content while scrolling. Check out an example below to get a better idea of it.

                                Parallax HTML Structure
                                
                        <div class="parallax-container">
    <div class="parallax"><img src="images/parallax1.jpg"></div>
</div>
                            
                                Initialization
                                
                        $(document).ready(function(){
    $('.parallax').parallax();
});   
                            
                                Parallax Customization
                                
                                
                        The parallax container height is what defines how much of the image can be seen. This is set to a default of 500px. You can add your own style to override this.
.parallax-container {
    height: "your height here";
}
