Animation

As I said animating some vector properties is as simple as:

var paper = Raphael('canvas', 1024, 500);
var c = paper.circle(50, 50, 6).attr({fill : '#f00'});
c.animate({r : 10, fill : '#00f'}, 1000);

Here we change the radius and the background color of the circle for 1000 milliseconds.

The same thing can be done with any property with any other JavaScript library as jQuery. But as in jQuery, Raphael or whatever library the animation is not looping. That’s natural you can just change a property by animating it, but the looping animation suggests at least two animations. So it’s a developers job to implement this. Here’s a simple way to do this.

Two Way Animation

The solution here is using two functions calling each other.

var paper = Raphael('canvas', 1024, 500);
var c = paper.circle(50, 50, 6).attr({fill : '#f00'});

function a() {
    c.animate({r : 10, fill : '#00f'}, 1000, b);
}
function b() {
    c.animate({r : 6, fill : '#f00'}, 1000, a);
}
a();

Rounded Corners

That was a strange answer. Who’s making rounded corners with CSS?! on IE and more important how? There is a way to make it, but not entirely with CSS and HTML. The solution is with VML a subset of XML to deal with vectors, and CSS of course.

The original solution I found on snook.ca.

It is really working fine as described and shown in the example, but there are some issues as well. There is no way to setup background image on the container, and the width and height are behaving strange.

However this gives you an opportunity to make cross browser rounded corners with no scripting that slows down the page and except Opera it’s quite working!
