I added this script in the footer of my page that will flash the usually black background of the page once the page is loaded:
<script>
$(document).ready(function() {
function highlight_background(){
if(document.getElementById('content')) {
//fading background:
$('#content').css({backgroundColor:"#081108"});
$('#content').animate({backgroundColor: "black"}, 2000);
}
}
highlight_background();
)}
</script>
This looks great on black background like in my space online game.
But now I am planning to implement a feedback for the user in a serious application of a customer of mine that has white background. there it looks too playful.
Any idea how to manage an unobstrusive feedback once the page is loaded?
