Scales a single child element to fill the available space without resizing it. This control reacts to changes in the size of the container as well as changes in size of the child element. For example, a media query may result in a change in aspect ratio.
If you add more than one element to a ViewBox, only the first element is resized. If you must scale more than one element, wrap the set of elements in a DIV. See the example below for more information. Elements that do not scale, such as text, are not affected by the transforms used for the ViewBox.
