圆角丝带效果

这段代码有点长，但是圆角丝带效果很奇特！

HTML:

<div class="wrapper"> <div class="ribbon-wrapper-green"><div class="ribbon-green">NEWS</div></div> </div>CSS: .wrapper { margin: 50px auto; width: 280px; height: 370px; background: white; border-radius: 10px; -webkit-box-shadow:0px 0px 8px rgba(0,0,0,0.3); -moz-box-shadow:0px 0px 8px rgba(0,0,0,0.3); box-shadow:0px 0px 8px rgba(0,0,0,0.3); position:relative; z-index:90; } .ribbon-wrapper-green { width:85px; height:88px; overflow:hidden; position:absolute; top: -3px; right: -3px; } .ribbon-green { font: bold 15px Sans-Serif; color: #333; text-align: center; text-shadow: rgba(255,255,255,0.5) 0px 1px 0px; -webkit-transform:rotate(45deg); -moz-transform:rotate(45deg); -ms-transform:rotate(45deg); -o-transform:rotate(45deg); position: relative; padding: 7px 0; left: -5px; top: 15px; width: 120px; background-color: #BFDC7A; background-image: -webkit-gradient(linear, left top, left bottom, from(#BFDC7A), to(#8EBF45)); background-image: -webkit-linear-gradient(top, #BFDC7A, #8EBF45); background-image: -moz-linear-gradient(top, #BFDC7A, #8EBF45); background-image: -ms-linear-gradient(top, #BFDC7A, #8EBF45); background-image: -o-linear-gradient(top, #BFDC7A, #8EBF45); color: #6a6340; -webkit-box-shadow:0px 0px 3px rgba(0,0,0,0.3); -moz-box-shadow:0px 0px 3px rgba(0,0,0,0.3); box-shadow:0px 0px 3px rgba(0,0,0,0.3); } .ribbon-green:before, .ribbon-green:after { content: ""; border-top:3px solid #6e8900; border-left:3px solid transparent; border-right:3px solid transparent; position:absolute; bottom:-3px; } .ribbon-green:before { left: 0; } .ribbon-green:after { right: 0; }
