HTML
第1個例子中的HTML標記非常簡單,我們在頁面上創建了一個ul列表標記,並在其內部創建了幾個div來控制它的總體進度動畫,代碼如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

<ul id="progress">
<li>
<div id="layer1" class="ball"></div> <!-- layer1 control delay animation / ball is effect -->
<div id="layer7" class="pulse"></div> <!-- layer7 control delay animation / pulse is effect -->
</li>
<li>
<div id="layer2" class="ball"></div>
<div id="layer8" class="pulse"></div>
</li>
<li>
<div id="layer3" class="ball"></div>
<div id="layer9" class="pulse"></div>
</li>
<li>
<div id="layer4" class="ball"></div>
<div id="layer10" class="pulse"></div>
</li>
<li>
<div id="layer5" class="ball"></div>
<div id="layer11" class="pulse"></div>
</li>
</ul>
CSS 沒有什麼不同的,我們僅僅為ul標記創建了圖形動畫,請注意中間過程中的特別的動畫效果,這個效果要歸功於CSS3的延遲動畫特性,CSS代碼如下:

}
第2個CSS3 Loading動畫例子
HTML
在第2個例子中,我們將會創建一個loading進度條,僅僅是創建一個寬度為100%的容器,然後在裡面放一個class為expand的span標記,通過CSS3動畫進度條就能逐漸充滿整個屏幕,代碼如下:
1
2
3
<div id="content">
<span class="expand"></span>
</div>
CSS 這個樣式看起來比上一個簡單很多,這是最基本的設置,你可以根據你的需要改變它。

#content {

height:5px;
margin:50px auto;
background:#000;
}
.expand {
width:100%;
height:1px;
margin:2px 0;
background:#2187e7;
position:absolute;
box-shadow:0px 0px 10px 1px rgba(0,198,255,0.7);
-moz-animation:fullexpand 10s ease-out;
-webkit-animation:fullexpand 10s ease-out;
}
/* Full Width Animation Bar */
@-moz-keyframes fullexpand {
0% { width:0px;}
100%{ width:100%;}
}
@-webkit-keyframes fullexpand {
0% { width:0px;}
100%{ width:100%;}
}
第3個CSS3 Loading動畫例子
HTML
在最後一個例子中,我們利用opacity屬性重新創建了loading進度條,這裡我們將用控制層控制其准確的動畫時序。

</li>

</ul>
CSS 你看到的效果和第1個差不多,但重要的是你懂得了如何用CSS來制作如此美妙的效果。
