script.
  const preloader = {
    endLoading: () => {
      document.body.style.overflow = 'auto';
      document.getElementById('loading-box').classList.add("loaded")
    },
    initLoading: () => {
      document.body.style.overflow = '';
      document.getElementById('loading-box').classList.remove("loaded")

    }
  }
  window.addEventListener('load',()=> { preloader.endLoading() })

  if (!{theme.pjax && theme.pjax.enable}) {
    document.addEventListener('pjax:send', () => { preloader.initLoading() })
    document.addEventListener('pjax:complete', () => { preloader.endLoading() })
  }

新建css

新建source/css/progress_bar.css ，也可以不做这一步下面配置文件pace_css_url 这一项就要留空, 这一步是修改 pace 加载的胶囊 💊 样式用的

修改themes/butterfly/source/css/_layout/loading.styl ，注意其中颜色代码–anzhiyu-card-bgl 等需自行替换为自己的色值。

if hexo-config('preloader')
  .loading-bg
    display: flex;
    width: 100%;
    height: 100%;
    position: fixed;
    background: var(--anzhiyu-card-bg);
    z-index: 1001;
    opacity: 1;
    transition: .3s;

  #loading-box
    .loading-img
      width: 100px;
      height: 100px;
      border-radius: 50%;
      margin: auto;
      border: 4px solid #f0f0f2;
      animation-duration: .3s;
      animation-name: loadingAction;
      animation-iteration-count: infinite;
      animation-direction: alternate;
    .loading-image-dot
      width: 30px;
      height: 30px;
      background: #6bdf8f;
      position: absolute;
      border-radius: 50%;
      border: 6px solid #fff;
      top: 50%;
      left: 50%;
      transform: translate(18px, 24px);
    &.loaded
      .loading-bg
        opacity: 0;
        z-index: -1000;

  @keyframes loadingAction
    0% {
        opacity: 1;
    }

    100% {
        opacity: .4;
    }

添加自定义 css

在合适的地方加上自定义 css, 其中 background 的 url 即为 loading 的图片地址。

.loading-img {
  background: url(https://npm.elemecdn.com/anzhiyu-blog@2.1.1/img/avatar.webp) no-repeat center center;
  background-size: cover;
}

设置动画效果

最后修改_config.butterfly.yml 中preloader 选项, 改完以后source:  1 为满屏加载无pace胶囊,source:  2 为pace胶囊无满屏动画, source:  3 是两者都启用。
