	$(document).ready(function($) {
    
    /* Notes:  1. The javascript in this pen is not necessary and is only presented for clarity. 100 sets of b-tags are generated and prepended to each anchor tag; the b-tags can be hard-coded before the elements within the anchor tag, if desired. The b-tags, via CSS, then control the apparent movement of the background as the mouse moves over the anchor. Note that if a different amount of b-tags are generated then the CSS that controls the apparent movement of the background for each row and column of b-tags must be recalculated. 2. I am thinking that not hard-coding the 100 b-tags for each achor will save some 700 bytes of download for each anchor, so using JS to prepend the b-tags might be useful. 3. Not using a JS mousemove eent, even if throttled, ought to help with page responsiveness, especially with lots of anchors of this type potentially being present. */
