If you need to use getElementsByClassName on IE : <a href="http://robertnyman.com/2008/05/27/the-ultimate-getelementsbyclassname-anno-2008/" rel="ugc">http://robertnyman.com/2008/05/27/the-ultimate-getelementsbyclassname-anno-2008/</a><br />
Else with jQuery :<br />
<br />

<pre><code id="code-20-34950971-1">$(&quot;.myClass&quot;).css({&quot;width&quot;:swidth + 'px'});</code></pre>

Hi all,<br />
<br />
I am trying the following:<br />
<br />
var myDiv = document.getElementsByClas<wbr />sName('myC<wbr />lass');<br />
alert(myDiv);<br />
<br />
This is returning: [object HTMLCollection]<br />
<br />
I need to change all the width's of a class on my page...<br />
<br />
myDiv.style.width = swidth + 'px';<br />
<br />
It works on getElementById but not in Classes ... how can I get this to work please?<br />
<br />
THanks<br />
