• 使用Jquery,CSS3实现像GooglePlus那样的圆圈效果


            我们要实现像Google+ 那样圆圈效果, 不使用图片.这里只使用CSS3JQuery, 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:

    GoogleCircleHover

    您可能先了解CSS3, 可以参考这儿.

    希望对您WEB开发有帮助.
