    <p>I have a page that looks like this</p> <pre><code>----------------------------------- | ************* | | ************* | | ************* | | ************* | | ************* | | ************* | ----------------------------------- </code></pre> <p>The outer frame is the browser edge and thus the <code>&lt;body&gt;</code>, and the stars are a centred background image on the <code>&lt;body&gt;</code> element.</p> <p>Now, using javascript I'd like to add some aboslutely positioned DIVs each side of that background in order to extend it:</p> <pre><code>----------------------------------- |*********|*************|*********| |*********|*************|*********| |*********|*************|*********| |*********|*************|*********| |*********|*************|*********| |*********|*************|*********| ----------------------------------- </code></pre> <p>As the window is resized the centred background will move (to remain in the center of the window), so the divs on each side should move in consequence.</p> <p>Can anyone please suggest an approach to solving this issue?</p> <p>Side note on why I'm doing this:</p> <p>The background is large image, and I wish to have it repeated across the screen by flipping it as described here:</p> <p><a href="https://stackoverflow.com/questions/13287090/background-flipped-tiling-using-javascript">Background flipped tiling using Javascript</a></p> <p>The actual process of flipping was discussed in that question, whereas this question deals with the CSS/Javascript aspect of positioning.</p> <p>Note that in the case of non-capable browsers I'm happy leave the page as it is in the first diagram, with only the centred background.</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.

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).
