- Where to find it
- Labelled Width in the Widget Settings drawer (gear in the widget header).
- Per device
- Yes — you can set one value for every screen, or separate values for phone, tablet, and desktop.
- Underlying CSS
width
In plain English
By default the widget fills whatever space the host page gives it. Width lets you pin or size that outermost box.
For a readable centred embed, Max Width plus Margin of "auto" is usually a better recipe than a fixed Width alone.
When you would use it
- The widget must be an exact width rather than filling its host slot.
How to change it
- Open Widget Settings, then "Width", and pick a unit or auto.
One value, or one per device? Every input in this setting sits under a “Same value for all resolutions” checkbox. Leave it checked for a single value everywhere, or uncheck it to give phones, tablets, and desktops their own. How per-device values work.
Watch out for
- This setting is left out on the editing canvas so the drag-and-drop surface stays full size. Open Preview to see it applied.
