样式代码：

.blink {
    position: fixed;
    height: 100%;
    width: 100%;
    text-align: center;
    display: flex;
    display: -webkit-flex;
    align-items: center;
    line-height: 30px;
    justify-content: center;
    animation: blink 3s linear infinite;
    -webkit-animation: blink 3s linear infinite;
    -moz-animation: blink 3s linear infinite;
    -ms-animation: blink 3s linear infinite;
    -o-animation: blink 3s linear infinite;
}

目测可以先检查一下是否跟那个全角的冒号「：」有关～
