How to make a flashing div?

Question

I need a div to glow from a color to another and vice-versa. This is what I did using shadow animation jQuery Plugin: jsFiddle and it works well... but when I refresh the page it doesn't load and I get this error:

Maximum execution time of 30 seconds exceeded

How can I fix it?

Answer 1

I don't get an error, but just in case it works for you, try replacing

function(){
    shadow_normal();
}

with

function(){
    window.setTimeout(shadow_normal, 1);
}

and same with shadow_animar.
