the duration should be in milliseconds. &nbsp;You probably meant 0.5 secs. If that is the case try:<br />
$('#content').animate({opa<wbr />city: 0.25}, <b>500</b>);//500millisecs=0.5secs<br />
<br />
Also, make sure you call it once #content is ready/available:<br />

Hi I'm trying out the zepto.js library because it's so small...<br />

I wrote the simplest line:<br />
<br />
$('#content').animate({opa<wbr />city: 0.25}, 0.5);<br />
<br />
But it doesn't work, nothing happens?
