## **CSS Customization**

To customize transitions, follow the naming convention:
- `{transition-name}--init`
- `{transition-name}--show`
- `{transition-name}--hide`

Example:
```css
/* Custom fade transition */
.x-toast.fade--init { opacity: 0; }
.x-toast.fade--show { opacity: 1; transition: opacity 0.5s ease-in; }
.x-toast.fade--hide { opacity: 0; transition: opacity 0.5s ease-out; }
```
