jQuery CSS Opacity
Solution 1:
jQuery('#main').css('opacity') = '0.6';
should be
jQuery('#main').css('opacity', '0.6');
Update:
http://jsfiddle.net/GegMk/ if you type in the text box. Click away, the opacity changes.
Solution 2:
Try with this :
jQuery('#main').css({ opacity: 0.6 });
Solution 3:
Try this:
jQuery('#main').css('opacity', '0.6');
or
jQuery('#main').css({'filter':'alpha(opacity=60)', 'zoom':'1', 'opacity':'0.6'});
if you want to support IE7, IE8 and so on.
