Simple one: how to put <model-viewer> and an <mg ...> side by side

[motionmountain]

In my webpage, the < model-viewer ...> < /model-viewer > always takes a complete line.
It behaves like having a < br > built-in.

What can be done to have
< model-viewer ... >< /model-viewer > and < img ... >
displayed side by side on a html page?

We're styled internally as a display: block div. All the usual CSS layout stuff to should apply to MV the same as to a <div>.
