    <p>I am applying an <code>:after</code> pseudo element to the body displaying the name of my media query breakpoint like so:</p> <pre class="lang-css prettyprint-override"><code>body::after { content: 'medium'; display: none; } </code></pre> <p>The reason for doing this can be found here: <a href="http://adactio.com/journal/5429/" rel="nofollow">http://adactio.com/journal/5429/</a></p> <p>I want to get the content value of <code>:after</code> using javascript in IE8.</p> <p>This is how i am doing it for other browsers:</p> <pre><code>var breakpoint = window.getComputedStyle(document.body, ':after').getPropertyValue('content'); </code></pre> <p>But IE8 does not support <code>getComputedStyle()</code>, i know it supports <code>currentStyle</code> instead, but after a bit of trying i was unable to use it correctly.</p> <p>This is the kind of thing i was trying with no success:</p> <pre><code>var breakpoint = document.body.currentStyle.getPropertyValue('content'); </code></pre> <p>Anybody know how to do this?</p> <p><strong>Edit:</strong> After BoltClock's note i have now changed my css to this (one semi colon):</p> <pre class="lang-css prettyprint-override"><code>body:after { content: 'medium'; display: none; } </code></pre> <p>Before using two the content was not even appearing in IE8, so it would have had nothing to return. Unfortunately i still can't get IE8 to return the content.</p> <p>I am trying this:</p> <pre><code>if (style = document.body.currentStyle) { for (var prop in style) { if (prop === 'content') { alert(prop); } } } </code></pre> <p>I get nothing, but if i change <code>'content'</code> to some other property like <code>'backgroundColor'</code> it will alert something. So i'm thinking that even though msdn lists content as one of the available properties of <code>currentStyle</code> <a href="http://msdn.microsoft.com/en-us/library/ie/ms535231%28v=vs.85%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ie/ms535231%28v=vs.85%29.aspx</a> it does not actually return it, unless i'm doing something else wrong.</p>

    1. COIE8 doesn't support the double-colon version of `::after` either. If you need to support IE8, use `:after`.

    2. COThanks, i was hoping that would be the reason i couldn't get the value of the :after content but alas i still can't get ie8 to return anything.

    3. COProbably because `:after{}` does not count as the element's own style. Any chance you can use something like `document.styleSheets[0].cssRules`?

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.
