I Can't Understand The Purpose Of That Property,And What Is The Difference Between animation-fill-mode:none; And animation-fill-mode:forwards;?...

Hello There. I'am Making What It Seems Like A Function To Animate The Background Color Of An Element,But I Have A Problem. This Is The Code: <script> function color(id,duration,r_start,g_start,b_start,r_end,g_end,b_end) { var element=document.getElementById(id); var parameter=setInterval(colorGradually,50*duration); function colorGradually() { if (r_start==r_end && g_start==g_end && b_start==b_end) { clearInterval(parameter); } else { for (var i=r_start,var j=g_start,var k=b_start; i<r_end && j<g_end && k<b_end;i++,j++,k++) { element.style.backgroundColor="rgb("+i+","+j+","+k+")"; } } } } </script> <div id="test" style="width:100%;height:200px;background-color:rgb(128,128,128)"></div> <input type="button" onclick="color('test',1,128,128,128,255,255,255)" value="Change"> The Script Isn't Working At All. I've Checked The Script With Esprisma Code Validator And The Code Was Syntactically Valid,But I Can't Recognize The Problem...

This Code Isn't Working: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> <script> $(document).ready(function(){ $("#area").animate({ backgroundImage:"url('image2.png')" },2000); }); </script> <style> #area { width:100%; height:600px; background-image:url("image2.png"); } </style> <div id="area"></div>

Hi, I am trying to come up with a preloader. The problem is none of the animations start. What I am trying to achieve is the following sequence: preloader_wrapper fade in, then fade out as soon as the document is loaded. JS: jQuery(document).ready(function($) {/* * Preloader */$('#preloader_wrapper').addClass('preloader_fadein');$(window).load(function(){$('#preloader_wrapper').addClass('preloader_fadeout');$('header *').css({ -webkit-animation-play-state: 'running'; -moz-animation-play-state: 'running'; -o-animation-play-state: 'running'; animation-play-state: 'running';});});}); CSS: .preloader_wrapper { position: absolute; top: 50%;}.preloader_fadein { -webkit-animation: preloader_fadein 2s ease; -moz-animation: preloader_fadein 2s ease; animation: preloader_fadein 2s ease;}@keyframes preloader_fadein { from { opacity: 0; left: 45%; } to { opacity: 1; left: 50%; }}.preloader_fadeout { -webkit-animation: preloader_fadeout 2s ease; -moz-animation: preloader_fadeout 2s ease; animation: preloader_fadeout 2s ease;}@keyframes preloader_fadeout { from { opacity: 1; left: 50%; } to { opacity: 0; left: 55%; }}.header * { -webkit-animation-play-state: paused; -moz-animation-play-state: paused; -o-animation-play-state: paused; animation-play-state: paused;}

Started on the 2D tutorial and could not get animation to work - IS this explained further along in the animation section of CSS3? Or, is animation in JavaScript? I was hoping it wasn't a computer setting problem because when I was in the CSS3 2D transformation tutorial, the animation was not working. Thanks Rich

Hi all - My end goal is a static image that, when hovered, will darken slightly and white text will slide up and fade in from the bottom of the frame. But I'm not sure of two things: first, how do I have a single div container/hover "area" trigger both animations, rather than just the top-most one? Second, as the animation stands now, it only triggers when I hover over the image - which has been positioned out of frame so as to make the fade/slide-in animation look right. How can I specify the affected hover area so that it triggers an image to arrive from out of frame? Since I suspect that was really unclear, here's what I've got so far. #backgroundimg img { /* static image background*/position: absolute;top: 0;left: 0;z-index: 2;} #anisquare { /* dark square that fades in on hover; width and height are same dimensions as my background image */width:293px;height:272px;position: absolute;top:0;left:0;z-index: 3;background:black;opacity:0;transition:opacity .3s;-moz-transition:opacity .3s; /* Firefox 4 */-webkit-transition:opacity .3s; /* Safari and Chrome */-o-transition:opacity .3s; /* Opera */} #anisquare:hover{opacity: 0.38;} #fadingtext { /* here's where my confusion starts... */position:absolute;top: 0;left: 0;width: 293px;height: 272px;} #fadingtext img {position:absolute;top: 280px;left: -1px;width: 191px;height: 45px;z-index:4;opacity:0;-webkit-transition: all 0.3s ease;-moz-transition: all 0.3s ease;-o-transition: all 0.3s ease;} #fadingtext:hover { opacity: 1; top: 228px;left: -1px;} As it stands, the image only rolls up and appears when I mouse over the image. I would like it to animate when I mouse over the area specified by the #fadingtext div tag. Also, at the moment, both hover animations are mutually exclusive - eventually I want hovering over a single div container to activate both of them. Many, many thanks in advance!!
