Utilities for controlling how an element's background is positioned relative to borders, padding, and content.
Use bg-origin-border, bg-origin-padding, and bg-origin-content to control where an element’s background is rendered.
<div class="bg-origin-border p-4 border-4 border-dashed ..." style="background-image: url(...)">
1
</div>
<div class="bg-origin-padding p-4 border-4 border-dashed ..." style="background-image: url(...)">
2
</div>
<div class="bg-origin-content p-4 border-4 border-dashed ..." style="background-image: url(...)">
3
</div>To control the background-origin property at a specific breakpoint, add a {screen}: prefix to any existing background-origin utility. For example, use md:bg-origin-padding to apply the bg-origin-padding utility at only medium screen sizes and above.
<div class="bg-origin-border md:bg-origin-padding ...">

默認情況下, 只有 響應式 的 background-origin 變化模式 (variants) 會產生。
在 tailwind.config.js 的 variants 區塊中變更 backgroundOrigin 屬性來決定有哪些變化模式會生成。
舉個例子來說，這個設定將會生成 響應式 和 hover 的變化模式。
// tailwind.config.js
module.exports = {
variants: {
extend: {
// ...
+ backgroundOrigin: ['responsive', 'hover'],
}
}
}如果你不打算在專案中使用 background-origin 功能，可以在你的設定檔裡的 corePlugins 屬性中將 backgroundOrigin 設定為 false 來停用功能：
// tailwind.config.js
module.exports = {
corePlugins: {
// ...
+ backgroundOrigin: false,
}
}
