小程序引入外链字体库

uni.loadFontFace({
     family: 'YouSheBiaoTiHei-2',
     source: 'url("https://file.wonder-link.net/YouSheBiaoTiHei-2.ttf")',
     success(res) {
         // self.setData({ loaded: true })
     }
 });

<div class="title-bg">{{ infoDetails.subtitle }}</div>

text-align: center;
font-size: 70rpx;
font-weight: bold;
color: #fff;
position: absolute;
top: 28%;
margin: auto;
left: 0;
right: 0;
font-family: "YouSheBiaoTiHei-2";

效果
