Scaling buttons inside a container on hovering

I have a container layer (toolbar) in krpano that contains several icon buttons. The container’s width is dynamic, so it initially adjusts to the width of its children. Now I’d like to add a hover effect to the buttons: They should slightly change their size WITHOUT changing the size of the container. Unfortunately, animating the scale property also changes the size of the container. Is there a simple solution? Perhaps the container’s size could be frozen after all children have been added within an action? When is a good time to read the values of pixelwidth and pixelheight and assign them to width and height?

Thanks for any hints!

Thanks for the advice, Tuur!

Unfortunately, I didn’t express myself quite correctly earlier. The container only adapts automatically to the children because I used `flowchildren` and `childflowspacing`. This causes layout shifts when a child is slightly scaled during a hover effect.

Now I’m doing away with `flowchildren` and calculating the children’s positions myself. In this case the container size doesn't change during hover effects.
