For small screens / Responsive behaviors
-
When rendering on smaller screens, enforce desiered
widthon the plugin container and plugin would try to fit in. -
The plugin renders at a smaller width (to fit in smaller screens) automatically, if the container is of slimmer than the configured
width. -
You can scale down the container on mobile and the plugin will fit in as long as it gets the minimum of
180pxto fit in.
Without Adaptive Width

- The plugin will render at the width specified, irrespective of the container width
