is there any feature in ArcGIS Dashboard to automatically resize the widget text/number based on different screens?
Thank you!
The Indicator widget will resize its text automatically for different screen sizes. The widgets themselves are sized by percentage, so they will maintain the same proportions across different screens.
Other widgets like List, Table, and Rich Text support in-line HTML styling, and you can define your font size with vw, or "view width".
<div style="font-size:8vw;">
Dynamic Text Size
</div>
