Transparent background for ArcGIS Dashboards and its elements.

[ZoevdbAT]

I'd like to have the option to set the background of an ArcGIS Dashboard to transparent, as well as the background of its elements. Sometimes when embedding the dashboard in other websites I need them to be transparent due to styling used for the sites. 

The current given options are Hex, RGB or HSL Syntax. But #0000ffff and for example 120, 100%, 50%, 0 are invalid. 

My thanks in advance.

rgba(255,255,255,0) is also invalid.

This still needs to happen right?

@TomThompson2 Yep!

@ZoevdbAT  Us users need this to be an option.  It seems like a hex code should work but they don't... The examples you shared would also work for me.  "The current given options are Hex, RGB or HSL Syntax. But #0000ffff and for example 120, 100%, 50%, 0 are invalid. "

Please make this happen Esri
