One of the CSS3 properties designers have been longing the most for is undoubtedly the border-radius property. With CSS3 border-radius property it’s possible to create the so popular rectangles with rounded corners exclusively via CSS - no images needed. Cross-browser compatibility CSS3 aren’t supported by all browsers yet. The border-radius property is supported by Firefox (since version 3.0), Safari (since version 3.1) and Chrome (since the first version), but it’s not supported by Internet Explorer or Opera (it should be implemented in Opera 10). Since CSS3 aren’t standard yet, you must add prefixes to border-radius in order to work with the browsers that support it. If you want to work it with Firefox, you must write -moz-border-radius in the CSS; if you want it to work with Safari/Chrome, it’s -webkit-border-radius. Note that although Firefox, Safari and Chrome support this property, they do so in slightly different modalities.
