我们要实现像Google+ 那样圆圈效果, 不使用图片.这里只使用CSS3与JQuery, 先定义CSS:
1: <style type="text/css">
2: div.circle { 3: margin: 100px auto; 4: width:200px; 5: height:200px; 6: } 7: div.outer.hover { 8: -moz-transform: scale(1.45); 9: -webkit-transform: scale(1.45); 10: transform: scale(1.45); 11: } 12: 13: div.outer{ 14: position:absolute; 15: z-index:800; 16: -webkit-transition: all .2s ease-in-out; 17: -moz-transition: all .2s ease-in-out; 18: -o-transition: all .2s ease-in-out; 19: transition: all .2s ease-in-out; 20: background:transparent; 21: width:122px; 22: height:122px; 23: -webkit-border-radius: 61px; 24: -moz-border-radius: 61px; 25: border-radius: 61px; 26: border:1px solid #aaaaaa; 27: } 28: div.middle 29: { 30: margin:1px; 31: width:122px; 32: height:122px; 33: -webkit-border-radius: 61px; 34: -moz-border-radius: 61px; 35: border-radius: 61px; 36: background: #ececec; 37: z-index:900; 38: -webkit-transition: all .2s ease-in-out; 39: -moz-transition: all .2s ease-in-out; 40: -o-transition: all .2s ease-in-out; 41: filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ececec', endColorstr='#d8d8d8',GradientType=0 ); 42: background: linear-gradient(top, #ececec 0%,#d8d8d8 100%); 43: position:absolute; 44: 45: transition: all .2s ease-in-out; 46: background: -moz-linear-gradient(top, #ececec 0%, #d8d8d8 100%); 47: background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ececec), color-stop(100%,#d8d8d8)); 48: background: -webkit-linear-gradient(top, #ececec 0%,#d8d8d8 100%); 49: background: -o-linear-gradient(top, #ececec 0%,#d8d8d8 100%); 50: background: -ms-linear-gradient(top, #ececec 0%,#d8d8d8 100%); 51: } 52: 53: div.middle.hover { 54: -moz-transform: scale(1.4); 55: -webkit-transform: scale(1.4); 56: transform: scale(1.4); 57: } 58: div.inner 59: { 60: margin:14px; 61: 62: background:#3f96d1; 63: width:96px; 64: height:96px; 65: 66: font-size:11px; 67: color:#FFF; 68: line-height:96px; 69: text-align:center; 70: font-family:Arial; 71: 72: -webkit-border-radius: 48px; 73: -moz-border-radius: 48px; 74: border-radius: 48px; 75: 76: -webkit-box-shadow: inset 0px 1px 1px 0px #575757; 77: -moz-box-shadow: inset 0px 1px 1px 0px #575757; 78: box-shadow: inset 0px 1px 1px 0px #575757; 79: 80: border-bottom:1px solid #FFF; 81: 82: position:absolute; 83: z-index:1000; 84: 85: }86: </style>
引入JQuery:
1: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js" type="text/javascript">
2: </script> 3: 4: <script language="javascript" type="text/javascript">
5: $(function() {
6: $('div.circle').mouseover(function() {
7: $('div.outer').addClass('hover');
8: $('div.middle').addClass('hover');
9: });10: $('div.circle').mouseout(function() {
11: $('div.outer').removeClass('hover');
12: $('div.middle').removeClass('hover');
13: }); 14: }); 15: </script>目标的HTML片段:
<div class="circle"><div class="outer"></div><div class="middle"></div><div class="inner">Developers code</div></div>
好了,运动后效果图是这样的:
您可能先了解CSS3, 可以参考这儿.
希望对您WEB开发有帮助.
