Why Does My SVG Sub-Element Scale from the Top Left Instead of Its Center?

CSS Transform Origin Issue on SVG Sub-Element

When attempting to scale sub-elements within an SVG, users may encounter inconsistencies with the transform-origin point. Specifically, the origin is set to (0,0) based on the overall SVG rather than the sub-element's center. This behavior makes animations appear to "fly in" from the top left instead of scaling from the desired element's center.

To resolve this issue and set the transform-origin relative to the specific element being animated, the transform-box property needs to be included. By setting it to "fill-box," the transform-origin is bound to the sub-element's dimensions:

<code class="css">#animated-box {
  transform-box: fill-box;
  animation: scaleBox 2s infinite;
}</code>

This modification ensures that the sub-element, in this case, the animated box, scales from its own center rather than the origin of the entire SVG.
