    <p>You can do something like this, HTML:</p> <pre><code>&lt;body class="red"&gt; &lt;p&gt;Some text&lt;/p&gt; &lt;a href="#" id="paint-blue"&gt;paint blue&lt;/a&gt; &lt;a href="#" id="paint-red"&gt;paint red&lt;/a&gt; &lt;/body&gt; </code></pre> <p>CSS:</p> <pre><code>body.red { background-color: red; } body.red p { color: yellow; } body.blue { background-color: blue; } body.blue p { color: white; } /* Some more stuff */ </code></pre> <p>JS:</p> <pre><code>$("#paint-blue").click(function(event) { event.preventDefault(); $("body").removeClass("red").addClass("blue"); } $("#paint-red").click(function(event) { event.preventDefault(); $("body").removeClass("blue").addClass("red"); } </code></pre> <p>The idea is that depending on the class of the top level <code>body</code> element some elements on page will be styled differently.</p> <p>EDIT: The example page that you linked to uses cookies to store the chosen theme and from the looks of it, it always loads the yellow theme and then some <code>onload</code> JS checks the value in the cookie and changes the colours. <a href="http://www.tutorialspoint.com/javascript/javascript_cookies.htm" rel="nofollow">Here</a> is some random tutorial for setting and reading cookies using JS. And the <code>onload</code> thing would look something like:</p> <pre><code>$(document).ready(function() { // Should be easy to write if you look at the tutorial var colour = getColourFromCookie(); if (colour == 'blue') { $("#paint-blue").click(); } // red is default, no need to do anything }); </code></pre> <p>One thing that you could do better than the example site is that you could render a different page (different body class) depending on the cookie value instead of always rendering one version and then changing it on client side — at least on my computer there is a clear delay before JS kicks in and changes the colours.</p>

    1. COYes, but we are talking here about the background pattern of the page, about some div that will be shown or not. How that can be done? Many thanks for the answer!

    2. COYou can just as well change other CSS properties, `background-image`, `display: hidden` or whatever else you want. Look here: http://www.csszengarden.com/ to see how much you can change the page with just CSS. Of course you can also extend the `click` handler and do some manipulations in JS, but CSS should be enough for most things.

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).
