I'd like to speed up the fade()
function, but the arguments the function accepts are about opacity, not speed. How can I do it?
Thanks
You can set a new tween duration like:
$('slow').set('tween', {duration: 5000});
$('fast').set('tween', {duration: 100});
$$('div').fade();
<script src="https://ajax.googleapis.com/ajax/libs/mootools/1.5.1/mootools-yui-compressed.js"></script>
<div id="slow">I'm going to fade slowly!</div>
<div id="normal">I'm going to fade normal speed!</div>
<div id="fast">I'm going to fade fast!</div>
