(二)動效制作與詳解(詳解見代碼塊中的注釋!!!)
動效作品相機(最終效果)
1.搭建基本形狀
(代碼如下)
body{
background-color:#343C4C;min-width: 800px;min-height:400px;
}
/*定義背景顏色和最小寬高*/
.flat-anim{
display:block; position:absolute; width:264px; height:265px;
background:#6FDABB; border-radius:42px; top:50%; left:50%;
margin:-132px 0 0 -132px;
-webkit-box-shadow:
0 12px 0 -6px rgba(0,0,0,0.2);
}
/*display:block; 讓對象成為塊級元素,一般都是用display:none和display:block來控制層的顯示。
position:absolute;絕對定位,是將div的位置固定的,也就是用瀏覽器的絕對位置的顯示div,
border-radius圓角半徑,-webkit-box-shadow:對象的陰影設置(相機鏡頭的同心圓都是用陰影來寫的)*/
.flat-anim:before{
content:""; background-color:#282e3a; width:26px; height:26px;
border-radius:26px; position:absolute; top:20px; left:20px;
-webkit-box-shadow:
0 0 0 2px #1A4B46,
0 0 0 4px #282e3a,
0 6px 0 6px rgba(0,0,0,0);
}
/*content:"";插入內容,不寫這句話,整個代碼塊是不會起作用的。*/
.flat-anim:after{
content:"";
background-color:#C72E31; width:44px; height:20px;
border-radius:8px; position:absolute;
top:20px; right:24px;
}
.eye{
width:38px; height:38px; border-radius:38px;
background:#1E3E3C; display:block; margin:60px auto ;
z-index:20; position: relative;
-webkit-box-shadow:
0 0 0 22px #1A4B46,
0 0 0 30px #1E3E3C,
0 0 0 45px #ecf0f1,
0 10px 0 45px rgba(0,0,0,0.2);
}
.eye:before{
content:"";
background:#568E7C;width:30px;height:30px;
border-radius:30px;position:absolute;
top:-16px;left:-16px;
}
.eye:after{
content:'';background:#266C67;
width:16px;height:16px;position:absolute;
top:30px; left:30px; border-radius:16px;
}
.bottom{
width:264px; height:112px; display:block;
position:absolute; z-index:10;
background:#D94C4E; border-radius: 0 0 38px 38px;
bottom:0; left:0; border-top:15px solid #C72E31;
}
.bottom:before{
content:"";display:block;background:#282e3a;
width:140px;height:30px;margin:14px auto;
}
.bottom:after{
content:""; position:absolute;
top:30px; left:84px;
width:96px; height:70px;
display:block; background: #ecf0f1;
border-top:8px solid #c3d1dd;
border-bottom:14px solid #C72E31;
}
2.制作上半部鏡頭動畫
(代碼如下)
.eye,
.flat-anim:before,
.flat-anim:after {
-webkit-animation: eyeAnimation 5s infinite;
}
.flat-anim:before{
-webkit-animation-delay: 50ms;
-moz-animation-delay: 50ms;
-o-animation-delay: 50ms;
animation-delay: 50ms;
}
/*animation-delay動畫延遲,-moz-(Firefox瀏覽器) ,-o(Opera瀏覽器),-webkit(Safari 和 Chrome瀏覽器)是為了瀏覽器的兼容,所以一定要寫全。*/
.flat-anim:after{
-webkit-animation-delay: 150ms;
-moz-animation-delay: 150ms;
-o-animation-delay: 150ms;
animation-delay: 150ms;
}
@-webkit-keyframes eyeAnimation{
0%{ opacity:0; -webkit-transform:scale(0.1);}
12%{ opacity:0; -webkit-transform:scale(0.1);}
13%{ opacity:1; -webkit-transform:scale(0.1);}
20%{ opacity:1; -webkit-transform:scale(1.4);}
25%{ -webkit-transform:scale(1);}
95%{ opacity:1; -webkit-transform:scale(1);}
100%{ opacity:0; -webkit-transform:scale(0.1);}
}
/*@-webkit-keyframes關鍵幀動畫,通過關鍵幀動畫來制作鏡頭的動效*/
3.制作相機出照片的效果
(代碼如下)
.bottom:before{
-webkit-animation: bottomAnimation 5s infinite;
}
@-webkit-keyframes bottomAnimation{
0%{ opacity:0; width:0;}
21%{ opacity:0; width:0;}
22%{ opacity:1; width:8px;}
25%{ opacity:1; width:165px;}
26%{ opacity:1; width:140px;}
95%{ opacity:1; width:140px;}
96%{ opacity:0; width:0;}
100%{ opacity:0; width:0;}
}
.bottom:after{
-webkit-animation:bottomAfterAnimation 5s infinite;
}
@-webkit-keyframes bottomAfterAnimation{
0%{ opacity:0; height:0; border:0;}
25%{ opacity:0; height:0; border:0;}
26%{ opacity:1; height:0; border:0;}
26%{ opacity:1; height:0; border:2;}
28%{ opacity:1; height:0; border-top-width:16px;}
28%{ opacity:1; height:40px; border-top-width:16px;border-bottom-width:14px;}
95%{ opacity:1; height:40px; border-top-width:16px;border-bottom-width:14px;}
100%{ opacity:0; height:0; border:0;}
}
4.整體加入旋轉動畫
(代碼如下)
.flat-anim{
-webkit-animation: flatAnimation 5s infinite;
}
@-webkit-keyframes flatAnimation{
0%{-webkit-transform: rotate(50deg) scale(0.5);}
13%{-webkit-transform: rotate(360deg) scale(1.2);}
20%{-webkit-transform: rotate(360deg) scale(1);}
95%{-webkit-transform: rotate(360deg) scale(1);}
100%{-webkit-transform: rotate(410deg) scale(.5);}
}
/*小技巧:盡量把可以寫在一起的代碼合并,養成良好的習慣,如果動效復雜就注釋起來,一部分一部分做*/
5.HTML代碼
<div class="flat-anim animation">
<span class="eye"></span>
<span class="bottom"></span>
</div>
