¥Using a custom value
使用 object-[<value>] 语法 根据完全自定义的值设置 object position：
<img class="object-[25%_75%] ..." src="/img/mountains.jpg" />对于 CSS 变量，还可以使用 object-(<custom-property>) 语法：
<img class="object-(--my-object) ..." src="/img/mountains.jpg" />这只是简写，用于 object-[var(<custom-property>)] 它会自动为你添加 var() 函数。
响应式设计(Responsive design)
¥Responsive design
在 object-position 工具前面使用断点变体如 md: 仅在 medium 屏幕尺寸及以上时应用工具：
<img class="object-center md:object-top ..." src="/img/mountains.jpg" />请参阅 变体文档 详细了解如何使用变体。
