CSS3實作10種Loading效果方法

用CSS3實作了幾個常見的Loading效果，雖然很簡單，但還是分享一下，順便也當是做做筆記…

第1種效果：

程式碼如下：

<p class="loading">  
        <span></span>  
        <span></span>  
        <span></span>  
        <span></span>  
        <span></span>  
</p>

.loading{   
            width: 80px;   
            height: 40px;   
            margin: 0 auto;   
            margin-top:100px;   
        }   
        .loading span{   
            display: inline-block;   
            width: 8px;   
            height: 100%;   
            border-radius: 4px;   
            background: lightgreen;   
            -webkit-animation: load 1s ease infinite;   
        }   
        @-webkit-keyframes load{   
            0%,100%{   
                height: 40px;   
                background: lightgreen;   
            }   
            50%{   
                height: 70px;   
                margin: -15px 0;   
                background: lightblue;   
            }   
        }   
        .loading span:nth-child(2){   
            -webkit-animation-delay:0.2s;   
        }   
        .loading span:nth-child(3){   
            -webkit-animation-delay:0.4s;   
        }   
        .loading span:nth-child(4){   
            -webkit-animation-delay:0.6s;   
        }   
        .loading span:nth-child(5){   
            -webkit-animation-delay:0.8s;   
        }

##PS：CSS樣式程式碼其實很多重複，主要就是動畫不一樣，但為了方便以後直接拿來用，就先不整理了。
