transform-box
Defines the bounding box that a transform (like a rotation or scale) is relative to. This is especially important for SVG elements where you might want to rotate an object around its own center instead of the SVG's top-left corner.
Usage example
svg .gear {
transform-origin: center;
/* Ensures the gear rotates around its own center, not the SVG viewport coordinate (0,0) */
transform-box: fill-box;
transform: rotate(45deg);
