Vega-lite responsive size for column encoding facet chart - vega-lite

Question

I have a question on how might i ensure the width/height of facet chart? it seemed that the facet has limitation in following container height/width and doesn’t seem to allow for autosizing. I’m looking to implement a responsive, resizable facet chart
Here's my vega-lite config that im trying to make it responsive. So far setting width, or autosize wouldn't work.
