CSS3 Tutorials: Rounded Corners

This tutorial is on creating rounded corners effect with the aid of CSS3. This effect is achieved using “border-radius” property and really saves our time which was wasted in creating round-edged border images in Photoshop and then being used in web designs. For now, this effect is only visible in latest versions of Mozilla Firefox, Chrome, Safari and Opera and not in IE yet. But, Microsoft has confirmed the CSS3 support in Internet Explorer 9. And, have a look at the update for CSS3 Border Radius property in IE9 Test Drive page.
