    <p>I am looking for help / a point in the right direction / or a solution for a flicker/jump, when scrolling on a looping/infinite website, which can be seen in <a href="http://jsfiddle.net/djsbaker/j3d8r/1/" rel="nofollow">this fiddle</a>.</p> <p>What seems to be causing the jump is:</p> <p>"<code>$(window).scrollTop(half_way - child_height);</code>", and what could also be a Chrome windows scrollTop bug, but it is happening in all browsers at the moment.</p> <p>If I remove "<code>- child_height</code>" there is no longer a flicker but the page no longer scrolls correctly, which can be seen in <a href="http://jsfiddle.net/djsbaker/x5Tsp/3/" rel="nofollow">this fiddle</a>.</p> <p>Also, on the very first scroll the right hand column jumps up by three boxes - also because of '<code>half_way</code>', which I can fix by giving it a "<code>bottom: -600px;</code>"</p> <p>The full code:</p> <p><a href="http://jsfiddle.net/djsbaker/j3d8r/1/" rel="nofollow">http://jsfiddle.net/djsbaker/j3d8r/1/</a></p> <pre><code>var num_children = $('#up-left').children().length; var child_height = $('#up-left').height() / num_children; var half_way = num_children * child_height / 2; $(window).scrollTop(half_way); function crisscross() { $('#up-left').css('bottom', '-' + window.scrollY + 'px'); $('#down-right').css('bottom', '-' + window.scrollY + 'px'); var firstLeft = $('#up-left').children().first(); var lastLeft = $('#up-left').children().last(); var lastRight = $('#down-right').children().last(); var firstRight = $('#down-right').children().first(); if (window.scrollY &gt; half_way ) { $(window).scrollTop(half_way - child_height); lastRight.appendTo('#up-left'); firstLeft.prependTo('#down-right'); } else if (window.scrollY &lt; half_way - child_height) { $(window).scrollTop(half_way); lastLeft.appendTo('#down-right'); firstRight.prependTo('#up-left'); } } $(window).scroll(crisscross); </code></pre>

    1. COTo avoid flicker you need to i) Clone the parent element you're modifying. ii) Modify the cloned version iii) Replace the original version with the modified cloned version. Sorry, couldn't actually get it working in fiddle. (You'll need to change from using IDs to using classes as a first step.)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
