    <p>The color and the thickness of the lines are defined by the &lt;LineStyle> node in the resulting KML file. You can easily change them. </p> <pre><code>&lt;LineStyle&gt;&lt;color&gt;660000FF&lt;/color&gt;&lt;width&gt;0.1&lt;/width&gt;&lt;/LineStyle&gt; </code></pre> <p>Just remember that the encoding of the four hex bytes for the color is a bit unusual: &nbsp; <strong>Alpha, B, G, R</strong></p> <p>So 660000FF is Red (#FF on position 4) with an alpha-transparency of about 26% (#66 on position 1).</p> <p>The KML reference with all the details can be found here: <br> <a href="https://developers.google.com/kml/documentation/kmlreference" rel="nofollow">https://developers.google.com/kml/documentation/kmlreference</a></p> <p>The Birdtheme Google Maps tool (your link) allows you to directly play around with the LineStyles by simply clicking the <em>"Style&nbsp;options"</em> button!</p> <p><strong>EDIT:</strong></p> <p>If you need multiple outlines around a polygon path (i.e. highway style) you can paint the same polygon multiple times with different widths and colors. Here is a rough example how this could be implemented:</p> <pre><code>&lt;Style id="outerLine"&gt; &lt;LineStyle&gt;&lt;color&gt;FF0000FF&lt;/color&gt;&lt;width&gt;6&lt;/width&gt;&lt;/LineStyle&gt; &lt;/Style&gt; &lt;Style id="innerLine"&gt; &lt;LineStyle&gt;&lt;color&gt;FFFFFFFF&lt;/color&gt;&lt;width&gt;3&lt;/width&gt;&lt;/LineStyle&gt; &lt;/Style&gt; &lt;Placemark&gt; &lt;styleUrl&gt;#outerLine&lt;/styleUrl&gt; &lt;LineString&gt;&lt;coordinates&gt;6.0,48.0,0 18.0,50.0,0 16.0,41.0,0&lt;/coordinates&gt;&lt;/LineString&gt; &lt;/Placemark&gt; &lt;Placemark&gt; &lt;styleUrl&gt;#innerLine&lt;/styleUrl&gt; &lt;LineString&gt;&lt;coordinates&gt;6.0,48.0,0 18.0,50.0,0 16.0,41.0,0&lt;/coordinates&gt;&lt;/LineString&gt; &lt;/Placemark&gt; </code></pre> <p>With this technique the inner line is painted on top of the outer line. Unfortunately this limits the possibilities of making the whole ensemble semi-transparent: If you make the inner line semi-transparent it will not only show the background but also the color of the outer line shining through.</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.
