What use instead of css() for pseudo elements?
<p>guys. I have a little problem today... Code is below:</p>

<pre><code>var ttw = 10;
$('.insttip:after').css('left',(ttw/2-8)+'px');
</code></pre>

<p>Of course, it's not working. The reason is that <strong>css() function</strong> adds css property using element's '<em>style</em>' attribute. <strong>$('.insttip:after')</strong> is a pseudo element, so it has no '<em>style</em>' attribute.</p>

<p>What should I do to solve this problem?</p>

<p>Thank you!</p>
