transform-box: view-box;

/* Global values */
transform-box: inherit;
transform-box: initial;
transform-box: unset;

Values

border-box
Uses the border box as reference box. The reference box of a table is the border box of its table wrapper box, not its table box.
fill-box
Uses the object bounding box as reference box.
view-box
Uses the nearest SVG viewport as reference box. If a viewBox attribute is specified for the SVG viewport creating element, the reference box is positioned at the origin of the coordinate system established by the viewBox attribute and the dimension of the reference box is set to the width and height values of the viewBox attribute.

Formal syntax

border-box | fill-box | view-box
