I spent a bunch of time creating this really cool Logo animation for my site! The logo animation i made is the same size as the logo image on my site and I can apply it to the site easily.
The problem is the logo on my site is set to start scaling down once the screen width reaches a certain point. It's set with a max width but also set to scale to the size of its parent div. My animation does not do this... I realized I need to figure this out before applying my logo animation to my site. Since it does not act in the same way... And i really dont wana use css scaling and media queries because that would be a mess.
How can I make it act in the same way and scale like the logo on our site?
Here my animation.

Code has been Updated. It uses the canvas effect and it is responsive and uses css3 animation as well. I tried to make the animation show both front and back of coin at the start and end of the animation :) Cheers!

You're setting an explicit width and working with explicit pixel values and coordinates. That's going to make it tricky. Try working all the coordinates as a percentage of the width, and then you can dynamically detect the width (or set it outside the class) and everything should scale. It's not a quick fix, but it's not very complicated either.

Not exactly an expert here but I tried to mess around with your codes. From what I see is that all the css parameters in the code are fixed pixels which makes the elements be not responsive to screen size.
You have to make the parent div fixed pixel (or responsive if you'd like) and then set all the child elements be responsive to the parent. This can be 100% of the parent's width.
Thus in this way when the screen size shrinks, you needn't worry about the elements getting disrupted. They will be all encapsulated in the parent div.
This is not exactly the perfect code you require but it will give you a good idea of what is happening here.
CSS
.animateVSS{ position:relative; width:100px; height:100px; } .vsslogocover{ position:absolute; z-index:2; width:100%; } .blackdrop{ position:absolute; width:100%; } #myCanvas{ background:black; position:absolute; z-index;4; width:100%; height:100%; border-radius:50%; } .coin { background-image: url("http://portalpacific.net/jsfid/vss-animated-front-logo1.png"); background-size:contain; border-radius: 50%; position: absolute; width:100%; -webkit-transition: 1.8s ease-in-out; -o-transition: 1.8s ease-in-out; transition: 1.8s ease-in-out; -webkit-transform-style: preserve-3d; -o-transform-style: preserve-3d; transform-style: preserve-3d; z-index:1; background-color: black; } .coin:before { background-color: black; background-image: url("http://portalpacific.net/jsfid/vss22-animated- back-logo-185x1821.png"); background-size: contain; content: ''; height: 70px; left: 0; position: absolute; top: 0; width: 70px; margin-top:15px; margin-left:15px; border-radius:100%; } HTML

I tweaked your css a bit to make use of percentage wherever possible, Just replace your CSS with this one and you will see that your logo is now responsive. You can tweak the percentage to make it wider or smaller to your liking:
rotate(); setInterval(rotate, 8000); #myCanvas{ position:relative; background:black; position:absolute; z-index;4; margin-top:-190px; margin-left:-190px; border-radius:100%; } .animateVSS { position: relative; width: 20%; max-width: 282px; max-height: 283px; padding-top: 20%; display: inline-block; } .vsslogocover { position: absolute; z-index: 2; width: 100%; height: auto; max-width: 282px; max-height: 283px; top: 0; } .coin { height: 70%; max-height: 182px; width: 66%; max-width: 185px; margin-top: 16%; margin-left: 17%; top: 0; position: absolute; background-image: url(http://portalpacific.net/jsfid/vss-animated-front-logo1.png); background-size: 100% 100%; border-radius: 100%; -o-transition: 1.8s ease-in-out; transition: 1.8s ease-in-out; -webkit-transform-style: preserve-3d; -o-transform-style: preserve-3d; transform-style: preserve-3d; z-index: 1; background-color: black; } .coin:before { background-color: black; background-image: url(http://portalpacific.net/jsfid/vss22-animated-back-logo-185x1821.png); background-size: 100% 100%; content: ''; left: 0; position: absolute; margin-top: 1px; -webkit-transform: translateZ(-5px); -o-transform: translateZ(-5px); transform: translateZ(-5px); border-radius: 100%; height: 100%; max-height: 182px; width: 100%; max-width: 185px; top: 0; } .blackdrop { position: absolute; opacity: 0; width: 100%; height: auto; max-width: 282px; max-height: 283px; top: 0; } #myCanvas { background: black; position: absolute; margin-left: 17%; border-radius: 100%; top: 0; width: 70%; max-width: 200px; max-height: 200px; height: auto; margin-top: 17%; }
