    Hello,
    I would like to have the origin of normal Verge3d annotations to be in the center of the annotation element instead of the top left like it usually is. How would I achieve that since the CSS transform and transform-origin properties don’t seem to work on annotation objects?

    I attached a picture of the way I have annotations now. Just would like the annotation center to also be at the object center instead of the way it is now.

    add negative margin-left for the CSS rule .v3d-annotation or you can set this value for an element by its id.

    Puzzles and JS coding. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

    Since every annotation is a different size I would just use its ID, get the width and make the margin-left that width / 2. That should work right?

    Not exactly. By default the origin is here, in the center of the circle.

    The diameter is 32px, so the left margin will be -(width-32)/2px

    Puzzles and JS coding. Fast and expensive.

    Yes, exactly. I didn’t mention subtracting the width just wanted to make sure I had the idea correct with accessing the individual annotation property.

    Thank you!! I’ll try it out today.
