 # Wheelzoom
 
-A small script for zooming IMG elements with the mousewheel/trackpad.  Wheelzoom works by replacing the img element's src with a transparent image, then using the original src as a background image, which can be sized and positioned. Wheelzoom is dependency free, doesn't add any extra elements to the DOM, or change the positioning of the IMG element.

 ## Usage:
-````javascript

+```javascript
 wheelzoom(document.querySelectorAll('img'));
 // or
-wheelzoom(document.querySelectorAll('img'), {zoom:0.05});
+wheelzoom(document.querySelectorAll('img'), {zoom: 0.05});
 // zoom sets the zoom percent.
