css代码：
* { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; } html { font-size: 10px; -webkit-tap-highlight-color: transparent; } body { margin: 0; padding: 0; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px; line-height: 1.42857143; color: #333; background-color: rgba(211,232,132,0.8); } .container { overflow: visible; } .main { position: relative; width: 90%; height:200px; margin:auto; } .colorful { overflow: visible; width: 100%; height: 100%; } .colorful > a { float: left; display: block; width: 50px; height: 50px; zoom:2; } .colorful > a:hover { -webkit-animation:infinite 2s ease-in-out start-roll; -moz-animation:infinite 2s ease-in-out start-roll; animation:infinite 2s ease-in-out start-roll; } @-webkit-keyframes start-roll{ 0% { -webkit-transform: rotate(0deg); /*chrome*/ -moz-transform: rotate(0deg); /*火狐*/ -ms-transform: rotate(0deg); /*IE*/ transform: rotate(0deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); zoom:1; } 50% { -webkit-transform: rotate(180deg); /*chrome*/ -moz-transform: rotate(180deg); /*火狐*/ -ms-transform: rotate(180deg); /*IE*/ transform: rotate(180deg); -webkit-transition: opacity 1s linear; transition: opacity 1s linear; opacity: 1; filter: alpha(opacity=100); zoom:2; } 100% { -webkit-transform: rotate(360deg); /*chrome*/ -moz-transform: rotate(360deg); /*火狐*/ -ms-transform: rotate(360deg); /*IE*/ transform: rotate(360deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); zoom:1; } } @-moz-keyframes start-roll{ 0% { -webkit-transform: rotate(0deg); /*chrome*/ -moz-transform: rotate(0deg); /*火狐*/ -ms-transform: rotate(0deg); /*IE*/ transform: rotate(0deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); } 50% { -webkit-transform: rotate(180deg); /*chrome*/ -moz-transform: rotate(180deg); /*火狐*/ -ms-transform: rotate(180deg); /*IE*/ transform: rotate(180deg); -webkit-transition: opacity 1s linear; transition: opacity 1s linear; opacity: .5; filter: alpha(opacity=50); } 100% { -webkit-transform: rotate(360deg); /*chrome*/ -moz-transform: rotate(360deg); /*火狐*/ -ms-transform: rotate(360deg); /*IE*/ transform: rotate(360deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); } } @keyframes start-roll{ 0% { -webkit-transform: rotate(0deg); /*chrome*/ -moz-transform: rotate(0deg); /*火狐*/ -ms-transform: rotate(0deg); /*IE*/ transform: rotate(0deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); } 50% { -webkit-transform: rotate(180deg); /*chrome*/ -moz-transform: rotate(180deg); /*火狐*/ -ms-transform: rotate(180deg); /*IE*/ transform: rotate(180deg); -webkit-transition: opacity 1s linear; transition: opacity 1s linear; opacity: .5; filter: alpha(opacity=50); } 100% { -webkit-transform: rotate(360deg); /*chrome*/ -moz-transform: rotate(360deg); /*火狐*/ -ms-transform: rotate(360deg); /*IE*/ transform: rotate(360deg); -webkit-transition: opacity .3s linear; transition: opacity .3s linear; opacity: .5; filter: alpha(opacity=50); } }
js代码：
(function (window) { var document = window.document; function on(elem, evtnm, eventhd) { var onevtnm = 'on' + evtnm; elem[onevtnm] = eventhd; } function grc() { var val = [], i = 0; while (++i 0) { a = document.createElement('a'); a.style.backgroundColor = grc(); df.appendChild(a); } el.appendChild(df); } on(window, 'load', function () { fbc(); }); })(window)
希望本文所述对大家学习javascript程序设计有所帮助。
