    <p>As others have said both are valid and will do the trick. I'm not 100% convinced that they are identical though. If you have some style cascading going on then they could in theory produce different results since they are effectively overriding different values.</p> <p>For example. If you set "border: none;" and then later on have two different styles that override the border width and style then one will do something and the other will not.</p> <p>In the following example on both IE and firefox the first two test divs come out with no border. The second two however are different with the first div in the second block being plain and the second div in the second block having a medium width dashed border.</p> <p>So though they are both valid you may need to keep an eye on your styles if they do much cascading and such like I think.</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;style&gt; div {border: 1px solid black; margin: 1em;} .zerotest div {border: 0;} .nonetest div {border: none;} div.setwidth {border-width: 3px;} div.setstyle {border-style: dashed;} &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="zerotest"&gt; &lt;div class="setwidth"&gt; "Border: 0" and "border-width: 3px" &lt;/div&gt; &lt;div class="setstyle"&gt; "Border: 0" and "border-style: dashed" &lt;/div&gt; &lt;/div&gt; &lt;div class="nonetest"&gt; &lt;div class="setwidth"&gt; "Border: none" and "border-width: 3px" &lt;/div&gt; &lt;div class="setstyle"&gt; "Border: none" and "border-style: dashed" &lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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.
