    <p>Hey, I have a jQuery particle engine (that I'm using as an excuse to learn about easing mostly) - but the little elements won't rotate - here's my code (and a fiddle - see bottom of question):</p> <pre><code>function rotate(degree, ele) { $(ele).css({ '-webkit-transform': 'rotate(' + degree + 'deg)'}); $(ele).css({ '-moz-transform': 'rotate(' + degree + 'deg)'}); timer = setTimeout(function() { rotate(++degree); },5); } function particles() { var thisParticle; var particleSize = Math.floor(Math.random() * 24 + 8); var prependElement = $('body'); var speed = Math.floor(Math.random() * 2000 + 900); var distance = Math.floor(Math.random() * 500 + 200); var fallOffSpeed = speed / 2; var fallOff = distance + distance / 1.5; var top = 200; var rndR = Math.floor(Math.random() * 254); var rndG = Math.floor(Math.random() * 254); var rndB = Math.floor(Math.random() * 254); $(this).css({'background-color':'rgba('+rndR+','+rndG+','+rndB+', 1.0)'}); $(prependElement).prepend($('&lt;div&gt;', { "class" : "particles", "height": particleSize, "width": particleSize, }).css({ "background-color": "rgba("+rndR+","+rndG+","+rndB+", 1.0)", "position": "absolute", "-moz-border-radius": "1px", "border-radius": "1px", "opacity":0.75, "top": top, "z-index": "10" })); $.each($('.particles'), function () { var tmpEle = $(this); rotate(0,tmpEle); rndR = Math.floor(Math.random() * 254); rndG = Math.floor(Math.random() * 254); rndB = Math.floor(Math.random() * 254); if ($(this).css("opacity") == 0) { $(this).remove(); } else { thisOffset = $(prependElement).height()+$(this).offset().top+(top-$(this).height()); $(this).animate({ "left": [distance, 'linear'], "top": [thisOffset, 'easeOutBounce'] }, speed, 'linear').animate({ "left": fallOff, "opacity" : "0" }, fallOffSpeed, 'linear'); } }); setTimeout(particles, 250); } $(document).ready(function() { particles(); }); </code></pre> <p>[EDIT] @Howard solved my issue (I was missing the second argument on the setTimeout call). Next issue is why the rotation is a bit "funky".</p> <p><strong>NEW FIDDLE</strong>: <a href="http://jsfiddle.net/neuroflux/yLcaY/13/" rel="nofollow">http://jsfiddle.net/neuroflux/yLcaY/13/</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
