Gototop is a jQuery plugin which generates a custom scroll to top at the 'Bottom Right' of the webpage, allowing the user to scroll the webpage to the top with a smooth scrolling experience. The back to top button will be displayed when you scroll down the webpage and reach a specific position (default: 500px). You can also specify the top position where you want the webpage scroll back to.

How to use it:

1. Download the plugin and place the JavaScript file jquery.gototop.js after JQuery library.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="js/jquery.gototop.js"></script>

2. Create the back to top button and place it anywhere on the webpage.

<button class="gototop">
  <span>GO TO TÖP</span>
</button>

3. The CSS/CSS3 styles for the back to top button.
