Short Customizations: Optional

           - You  may change the arrows by changing the URLs in bold red.
           - To  may change the  background color of buttons by replacing  the blue text with your own  preferred color ( try our color code generator here)
           -  If in case you want to remove the "Go to top" button,  just remove the 1st set of code (it start with a .button_up) and to remove the "Go to bottom" button,  just remove  also the 2nd one ( it started with a .button_down).
