    <p>I believe it's because <code>a:hover</code> is more specific than <code>a:link</code>.</p> <p>If the original <code>a:hover</code> font-size was unspecified, it would be inherited from <code>a:link</code>. But since there is an <code>a:hover</code> specification, <code>a.myclass:hover</code> rather takes this value than the more "general" <code>a.myclass:link</code>.</p> <p>I read somewhere to think of the <code>a</code> pseudo-classes as "love hate": <code>:link</code>, <code>:visited</code>, <code>:hover</code>, <code>:active</code>, one more specific than the previous. If you define something for <code>a</code> or <code>:link</code>, it should be inherited by all the following pseudo-classes. That value can be overridden though, and the specificity of the pseudo-class is more important than the order in which the styles are defined or what other "real" classes are attached to the link.</p> <p>The reason it works differently in IE6 is that IE6 does it wrong, which shouldn't come as a surprise.</p> <p><strong>Differences in parsing (possibly backwards):</strong></p> <pre><code>a:hover { font-size: 8pt } a.myclass:link { font-size: 14px } a.myclass:hover { } </code></pre> <p><strong>How it should be:</strong></p> <blockquote> <p>Every <code>:hover</code>, regardless of <code>.class</code>, is 8pt.</p> </blockquote> <p><strong>How IE6 understands it:</strong></p> <blockquote> <p><code>:hover</code> is not in the same class as <code>.myclass:hover</code>. Since there's no size specified for <code>.myclass:hover</code>, let's inherit from the next higher available pseudo-class in the same class, which is <code>.myclass:link</code>. That makes <code>.myclass:hover</code> 14px.</p> </blockquote> <p><strong>Estimated lookup priorities:</strong></p> <pre><code>Others IE6 a a a.class a:link a:link a:hover a.class:link a.class a:hover a.class:link a.class:hover a.class:hover &lt;-- Lookup starts here, goes up. </code></pre>

    2. COIt doesn't "work" in IE6, it's actually borked in IE6. :o) Apparently the IE6 guys prioritized classes over pseudo-classes. While I'm not sure what the official specs says, most everybody else does "pseudo-classes over classes".

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).
