css3 - css transform是不是不会改变原来元素在文档中的位置和大小？

Question

是不是变换后就相当于在原来的位置挖了一个坑，原来该元素的布局都是保留下来的，我也不知道该怎么形容，就是transform变换前后都不会影响原来其他元素的布局？ 它是不是相当于position：absolute；使元素从原来的文档流脱出，只是这个是相对于它本身的absolute，并且把z-index提生到最高？

Answer 1

Transform is a rendering done by the browser on existing elements. It will not change the position or size. The implementation principle is definitely not position or z-index, it is an independent function

Answer 2

Transform is equivalent to relative, although it is moved or enlarged or reduced. Its position in the document flow remains unchanged and does not affect the layout.
