IE9、Firefox 4、Opera 10.5、Safari 5、Chrome 4、WebKit 532.5 支持 CSS3 边框半径。
最新的 jquerycurvycorners 2.1.1 使用-moz-border-radius而不是border-radius为旧浏览器创建角。如何将其替换为 border-radius, border-top-left-radius, border-top-right-radius, border-bottom-right-radius, border-bottom-left-radius?
您可以在 IE6-8 上看到的错误：
简而言之，jquerycurvycorners 必须适用于border-radius-curvycorners.html！
