### 若依管理系统 Loading Animation CSS/HTML

Source: https://github.com/richardgithub/smartlearn/blob/master/smartlearn-ui/index.html

Provides the HTML structure and CSS styling for a custom loading screen animation. This includes the main loader wrapper, the spinning loader element with its pseudo-elements for layered animation, and the logic for hiding the loader once the content is loaded. It also includes keyframe animations for the spinning effect and transitions for smooth state changes.

```html
html, body, #app { height: 100%; margin: 0px; padding: 0px; }
.chromeframe { margin: 0.2em 0; background: #ccc; color: #000; padding: 0.2em 0; }
#loader-wrapper { position: fixed; top: 0; left: 0; width: 100%; height: 100%; z-index: 999999; }
.no-js #loader-wrapper { display: none; }
#loader-wrapper .load_title { font-family: 'Open Sans'; color: #FFF; font-size: 19px; width: 100%; text-align: center; z-index: 9999999999999; position: absolute; top: 60%; opacity: 1; line-height: 30px; }
#loader-wrapper .load_title span { font-weight: normal; font-style: italic; font-size: 13px; color: #FFF; opacity: 0.5; }
```

```css

#loader-wrapper .loader-section.section-left { left: 0; }
#loader-wrapper .loader-section.section-right { right: 0; }
