    font-weight: 100;
    font-style: normal;
    font-size: 43px;
    line-height: 1.55;
　　// 主要代码 背景先渐变
    background: -webkit-gradient(linear,left top,left bottom,from(#baa898),to(#f66));
    background: linear-gradient(#baa898,#f66);
　　 background: -webkit-linear-gradient(#baa898,#f66);

　　//  以文本内容来剪辑背景
　　 background-clip: text; text-fill-color: transparent; 
　　 -webkit-background-clip: text;
　　//  让文本颜色透明
    -webkit-text-fill-color: transparent;
    -webkit-transition-delay: .4s;
    -moz-transition-delay: .4s;
    transition-delay: .4s;
    -webkit-transition-duration: 1s;
    -moz-transition-duration: 1s;
