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: 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: 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: 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: 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.
