    <p>If the div's size is dependent on the content (which I assume to be the case from your description) then you can retrieve the div's height using:</p> <pre><code>var divHeight = document.getElementById('content').offsetHeight; </code></pre> <p>And divide by the font line height:</p> <pre><code>document.getElementById('content').style.lineHeight; </code></pre> <p>Or to get the line height if it hasn't been explicitly set:</p> <pre><code>var element = document.getElementById('content'); document.defaultView.getComputedStyle(element, null).getPropertyValue("lineHeight"); </code></pre> <p>You will also need to take padding and inter-line spacing into account.</p> <p><strong>EDIT</strong></p> <p>Fully self-contained test, explicitly setting line-height:</p> <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-js lang-js prettyprint-override"><code>function countLines() { var divHeight = document.getElementById('content').offsetHeight var lineHeight = parseInt(document.getElementById('content').style.lineHeight); var lines = divHeight / lineHeight; alert("Lines: " + lines); }</code></pre> <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;body onload="countLines();"&gt; &lt;div id="content" style="width: 80px; line-height: 20px"&gt; hello how are you? hello how are you? hello how are you? hello how are you? &lt;/div&gt; &lt;/body&gt;</code></pre> </div> </div> </p>

    1. COIt's a good start except that the line-height may not always have been set. You should get that from computed style of the element.

    3. COOn second thoughts, the line-height need not always be numeric (or in pixels). So if your code relies on it and your CSS convention permits it, you should probably set a line height in pixels.

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).
