When you create an element with "new Element()", it only exists as a
javascript variable until you append the element to the DOM.
The $() function looks in the DOM for the element, which is why it is not
finding it.
Also, you may want to use Element#setStyle() instead of accessing the style
property directly. It's much more consistent cross-browser.
var a = new Element('div', {id: 'my_div'});
a.setStyle({width: '200px'});
